Bookmark Toolbar is very inconvenient for users who have a lot of bookmarks, because:
1 - In the toolbar fit just a few bookmarks, and horizontal scrolling is impractical.
2 - Toolbar take away space in height, which is at modern wide-screen monitors are always too low (due to more comfortable reading entire A4 documents and the like.)
3 - Opera's bookmark system does not allow importing bookmarks from other browsers (eg. From Firefox or Outlook)
These deficiencies are for many users with a lot Bookmark sufficient reason to renounce the use of the Opera, which is otherwise extremely lovable and good browser. Therefore, FOR EACH RECOMMENDATION IS (with Toolbar that can be also removed) TO INSTALLING THE SIDEBAR STRIP WITH BOOKMARK - LIST (modeled on the Firefox) WITH THE POSSIBILITY OF IMPORTS FROM MOZILLA AND OUTLOOK. The Bookmark-Toolbar should show the first ten bookmarks from the list, with the possibility of (temporary) removal from the site.
Sidebar list is more suitable than current solutions, because modern monitors have plenty of place across the width, and the Sidebar-list does not cover the content of the browser.
It's really sad they dropped Mail support, it was definitely one of the key features of the old Opera.
People defending the feature drop says "today users prefer to use web-based mails", of course they do, they DON'T HAVE AN ALTERNATIVE. A desktop mail client is just a pain and definitely a different concept, you got to install it, run it every time you want to check it, and also they use to be not usables and ugly. So you won't use it unless you are constantly receiving mails from multiple accounts (work or whatever).
Opera Mail was a real alternative to web-based mails, you got your mail client always there, hidden but active, you'll be noticed if any mail arrives, if you wanna access its way more easier to do it than going to gmail and it was CLEAN, it gave you exactly what you wanted with 4-5 customizing options, plus you got it linked to the "mailto:" so you didn't have to worry about that either.
They broke this a few versions back (not during the Presto -> Blink switch). I submitted a bug report a month ago to add the ctrl and alt + click functionality back to "Go to web address". DNA-31781. Really disappointing that they break such a useful feature.
I really the tile feature as well, it was what I primarily used opera for - I had two nagios status displays I could have side-by-side, and now I can't. I'm probably going to reinstall the old version.
Special colored buttons in the old Presto Opera versions were normally the result of a custom "skin" that could be added as a ***.zip file to the Opera browser 'skin' folder and selected via the Tools>Appearance>Themes menu path. Opera Mail is essentially an Opera browser 'suite' with the browser portion disabled or gutted, and because a lot of controls were disabled along with the browser portion, there may be no way to directly alter the skin/button effects... since I don't use or have installed Opera Mail, I've no way to look.
One approach might be to simply install a later-version of a Presto Opera browser (12.1x) and only use the Mail portion of it just as you now do Opera Mail. Then, assuming you could track down an appropriate skin file, you could insert that into Opera, select it, and then you'd have whatever colored/styled buttons the skin provided. Or you could go with the native "standard" skin buttons Opera provided. I always preferred the us.Opera.Fugue.5.1.0 skin for its compact, colored button renderings, and still use it within Opera 12.14... but different skins provide different button effects. With a selected Opera skin file in the Presto browser, you got whatever that skin file contained for all its buttons, and it was an all-or-nothing situation for all its button renderings unless you took the major effort to construct your own custom skin zip file. The challenge (hence the earlier-stated "assumption") with this approach is to track down a skin file you can download, since the old Opera versions are so dated now. At the end of the day, this may all represent a lot more effort than its worth just for what you're seeking.
Custom feed sources (and deletable defaults) is what Discover needs to have...
Synchronization with a feed service (e.g. Digg) would be excellent, although seeing the current direction of development, it's probably never going to happen.
The latest version, or at least the About says it's up to date:
Version: 26.0.1656.60 - Opera is up to date
Update stream: Stable
System: Windows 8.1 64-bit (WoW64)
Have to admit, I "misspoke", I've been killing the app rather than the individual processes (hadn't looked down the rather long list of processes to see the individual Opera ones); not sure if it will be possible to identify the effected process for the tab that's been hijacked, without a current page suffering from it I can't predict what sort of processing load it might display, if any, that might make it stand out.
Even so, a force close option would definitely be helpful, e.g. if a plugin on a page locks up.
