With new version 100.0.4815.76 (or the one .5x before), the bookmark folder names aren't partially not shown anymore. I'm sure they were there with the previous build .54(?)
Missing names of the folders are "Prio 1" and "Prio 2".
Folder names on the parent and childs are shown.
Another poll/request/wish to get tab grouping / stacking in Opera soon?

Also lost my tabs again from only one workspace, but not after the latest update:
Problem: After a download of a PDF I double clicked in the download notification and it should open - but it didn't for me - but it did on the 2nd monitor but on this I'd running my company laptop on HDMI 2 for days.
Only in rare cases I switch the 2nd monitor to HDMI 1 - my PC 2nd monitor.
Finally the Opera window 2 was open on HDMI 2 which I've never seen. Closed Opera on main window last night. Turned on today. All tabs lost on first workspace - maybe because from that I'd opened the PDF.
I noticed this situation ~ 10 days ago when I lost all tabs in another workspace. In this case I've moved a window to the 2nd monitor, closed the window first, then the main window. But next day I'd lost them also.
There should be a warning when closing the Opera main window (started first) and another Opera window is open so we can cancel and close the other Opera windows first - also on not active 2nd monitor.
However - my little small Opera startup script saved it all 
and I was able to restore the previous session with all tabs - more or less.
I recommend to use it until Opera has a better solution:
When opening a Markdown file (local double click or via http) it would be nice if Opera would display this file "nice" and not like as a simple .txt file.
Opera could offer various CSS styles (incl. plain txt of course) in preferences how to open .md files.
A right click context menu on the .md page to choose quickly another CSS style would be also good.
In March 2016, text/markdown was registered as RFC7763 at IETF.

and google around 
After another year, MS Edge 129.0.2792.79 still shows the as tab title the nice file name I've given my local PDF file.
Opera still shows the dumb "name" of the properties of a PDF.
E.g. I've over 200 security transactions PDFs per year and all have the same PDF title "BFOEncoder output" (generated by big companies). I want to see my local file name as for other files - e.g. when I open a TXT file with Opera.
When I open multiple PDF's with Opera I never know from the x open tabs which PDF is it. With the correct file name I would see that.
Currently I double click a PDF and MS Edge opens for it until Opera is willing to change it.
This situation is drives me nuts - more than missing tab stacking years ago and is the most stupid thing I've seen in Opera since version 6.
Don't tell me you can't change it! Make an option what a user wants to see!
Thanks
When I click on a Mixcloud link (which I receive per email) - Opera loads Mixcloud and before the mix starts to play Opera results in:
There is still enough memory - the problem is the process. Did not happen with Opera 66.
@aoirei Yes , Opera 12 tab stacking. All the time most used feature ever. Missing it so much. Just have 34 tabs open - from sw development, music, shares, social, lottery & betting .. would love to group / stack them within tab groups / tab stacking within one Opera window.
@burnout426 Thanks a lot. Will try with Opera 67 when it works. Had to downgrade.
@aoirei said in Another chance for tab grouping / stacking (when Chrome is working on it):
@leocg That does not look as useful as Opera 12 tab stacking. Chrome's solution is better.
Exactly.
I just tried it in the office where Chrome is standard browser.
It's not the same as Opera 12 tab stacking.
I can not use this Chrome grouping and disabled it.
Still waiting for classic easy usable Opera 12 tab stacking.
Thanks burnout426.
Done with bug report DNAWIZ-95025.
Fixed at least in 68.0.3618.63.
Again today this morning. It drives me nuts since I've 2 monitors.
I've closed the one open window on monitor 2. Then I watched a film on Netflix on monitor 1 (my main window) for an hour. Closed it. Turn on this morning. Opera tabs all gone. The session from monitor 2 with one tab opens.
Although I've tested it yesterday morning and it has worked. Close window on monitor 2, close on monitor 1. Start Opera again and last session of monitor 1 was there. But why not from yesterday to today?
@burnout426 I know I can save a workspace into a speed dial folder. But this I would have to do 6 times (workspaces) everytime I close Opera (beside delete the old ones)! There are always some tabs which are added (for to read) and deleted.
I've also looked into the sessions folder. There are only 2 sessions files (session_, tabs_) (one from yesterday and one today). And the one from yesterday is the time when I've closed Opera after watching the film on Netflix and went to bed. 2 session files are to less.
The best would be: Opera writes after every tab change (or after a few seconds when opening multiple tabs within a short time) the complete session (all open tabs in all workspaces) as text file: "workspace, URL" into a CSV file with time stamp in name. And this for e.g. 100 times (and checks from time to time if old files have to be deleted).
If an accident happens I can always find a session I want. A copy & paste of this CSV format (or multiple URL's only!) into the address field should open them in one go. (btw: This feature request I really miss since the first days of Opera! I often have a list of URL's which I want to open in multiple tabs in one step). These session + tab files are binary format, but found one open URL inside the session file from yesterday which I want.
Test: I've renamed the session+tab file from yesterday. Closed Opera. Deleted the current session+tab file, renamed the old files back. So only 2 files in folder (from yesterday before I went to bed). Started Opera. Opera opens again with session from monitor 2 with one tab. From where? I'm able to find URL's in this required session and tab file but it looks like Opera doesn't use it. But from where the info of monitor 2?
I've thought I use MS Edge as 2nd window but it's not possible because I open many links from email newsletters and the default browser opens of course.
Again this morning with version 85.0.4341.60 (!).
All tabs of window 1 are gone. Only the 2-3 tabs of window 2 will be shown although for 100 % I closed the 2nd window first, opened a new tab on 1st window "to have an update" and closed it, turned off PC.
In the "Sessions" folder of the profile I've only these 4 files (why not more older sessions?):
Session_13293928681899796
Session_13293951582247730
Tabs_13293868496103388
Tabs_13293951540479050
and the first Session + Tab file are timestamped with 4-5 minutes past midnight (when I turned off the PC).
The others are created this morning. I've closed Opera and deleted them. Started Opera - again - only tabs from window 2.
I've made a HEX view on the first Session file and see the tabs which I want. But after start, Opera shows me only those from window 2 which I've closed 100 % before window 1. Why?
Here the first bytes of the Sessions file. Where you can see "https://win2day.at/" which was the first tab of my a workspace and now I miss it when I start Opera.

What can I do?
Are there any bytes I can edit in these 2 files and then Opera uses my important tabs of window 1? Are there descriptions of the file formats anywhere?
I really had some temporary tabs open "to-do" (to read). It takes hours to find them in the history and I don't want to do that (I have a family with 2 kids).
Until this problem is solved it is clear I have to use another browser as 2nd window. What should I do?
Does the "Session Buddy" extension work with multiple workspaces? I've never used extensions since I use Opera 6. I was happy as it was (and is).
UPDATE:
When I also open the new created Session and Tab files in HEX view, I can see all the HTTP entries of the tabs I'm missing. They are there or here - but Opera doesn't open them.
Thanks a lot,
BR
At least with latest build 94.0.4606.76 it works now!
@leocg Thanks a lot - didn't see the important info on new Opera release pages.
Then it's more important to have back workspace names (before Opera 100) and not only icons (Opera 100) in the "Move To" menu of a tab. 
I don't know what happened, but definitely one session was running when I turned off the computer with one monitor. Monitor 2 is connected to company laptop only.
I just had it again.
Opera was running with some open tabs. But wasn't on PC.
Now we just had a power outage in our district.
Aftet that, started PC + Opera. No tabs there.
Copied the older session and tabs files away (left on screen shot).
Closed Opera
Deleted all files in Session dir.
Copied the older session and tabs files back.
Started Opera.
No tabs.
In the sessions folder are now my old session + tabs file + 2 new one.
So ? Did I something wrong?
Wouldn't it be good to have a longer running circle of files instead of a switch?
Of course the was a crash but I did nothing on my computer. I was typing a long email on company laptop when outage happend. The laptop battery saved my life however. ... So I hope Opera had flushed the files correctly to the SSD within these 20 minutes and they aren't destroyed. But it doesn't look so.
A better logic would be more circles instead of one new and old file pair would help. Also when Opera is running. Start a new session + tabs file up to 10 or 20 (specify in prefs) and delete the older ones. There is enough space today. This logic also helps when a crash happens.
PS: Unclear why I have 3 Session files after start of Opera after power outage? Time diff are 3 seconds
All a little bit unclear.
The older Tabs file is creation timestamp 16:19 and the corresponding Session timestamp is 20:35 .. ? Then I have one with 22:25, Tabs with 22:04 ..
I little bit mysterious the logic. I can't follow it. However I've copied the oldest files away - also from number in file name. But ... 
Finally sad. I'd opened multiple tabs for shopping of new furnitures for my son and pre-selected some. All gone now. Hard way to find them in history now ...
Best solution regarding the session files would be the "rotation":
When an user opens a specifc number of new tabs (user prefs) since the latest start, close the session file and start a new session file. Keep the closed session files until a specific number of times (user prefs). Delete the oldest session files which shouldn't be kept any more.
Example:
User setting for "new session file after opening new tabs: 4" and "number ob session files: 10".
Existing session files: #1
Start Opera with latest sesion file #1: 20 open tabs.
User opens 4 tabs and then the 5th.
Now 5 > 4, Opera closes the session file #1 and writes a new session file # 2
User opens 4 tabs and then closes 2 of them. The actual new count is 2 (4-2). Now user start 3 new tabs. New session file # 3 starts.
When the number of 10 session files is reached and the 11th is written to disc, then the #1 session file will be deleted because of the user prefs.
In this case we have a better (less) loss of tabs. Also when a crash happens, the older session file could be checked and used.
Wouldn't that be much easier?
I just wrote a small Opera start helper which copies the latest session and tabs files into a temp folder before Opera will be started.
So in case of an error (wrong close order, crash, etc.) you have the lastest sessions and can restore the latest correct session until a better session history logic is implemented in Opera.
Save the code below into CMD file and create a link on your desktop. Start Opera with this file in the future.
Old session or tabs files must be deleted manually e.g. every month. CMD isn't Bash to implement a better workaround and I have no time.
Last 11 days require 123 MB in my case. Nothing.

@burnout426 said in Tab name is always "BFOEncoder output" when I open local PDF file:
MS Edge doesn't support the title property at the moment, but since Chromium does, it's likely that Edge will start doing as Chromium eventually.
After 1 year and 2 month, MS Edge still is showing the nice local file name in the tab for the PDF and Opera doesn't.
Sad that I still have to use MS Edge for PDF's for the past 14 month and not Opera. Always at the end of the year when I sort out a few hundred security transaction PDFs it drives me nuts.
I hope Opera is able to make it better for users.
I want to see my local file name of the PDF and not the garbage of companies (like my bank where I'm software developer included!). Also they generate always the same name like "Security Transaction" or nothing (undefined) as title - not the specific things I want (which paper and transaction date etc. in file name). So the file names stored on our disc is essential and most useful and not the hardcore ideology of Opera.
Thanks
