I don't seem to have a My Folders option in the drop down menu.

1. Bring up a new Opera browser tab.
2. Left click on the Opera icon in the upper left corner of screen.
3. Click "Bookmarks" in the drop down manu
4. Hover over "My Folders" in the "Bookmarks drop down menu.
5. Right click on "My Folders"
6. Select "Sort alphabetically in the drop down menu.
7. Enjoy your sorted bookmarks!

...so in summary: all you have to do to implement a basic bookmark sort is pursue some ornate, tedious work around every time you add a bookmark.

Uhh, no. You just go into bookmarks in the Opera menu, right click a folder and sort. You are making it out to be a huge deal when its not. The default action when adding a bookmark is to put it at the top of the list. So, newer bookmarks are higher and older ones are lower. If you want to sort it yourself its literally 2 clicks away.

The problem is that that work around is slow, and it gets in the way (as so many other non-features in the post 12.15/17 opera tend to do). Sure the actual page access functionality has improved significantly, but the organizational features are severely lacking (see: progressive digression). So much so that this browser is actually resulting in massively reduced productivity for most skilled users who came from 12.15/17. It's kind of like how the windows CE/pocket pc platform had extremely powerful organization features (business user features [contact to calender seamlessness all wrapped in a logical layout, etc, etc, etc,]) that simply disappeared with later smartphone platforms (probably because those developing them totally forsake their original base [the business community, particularly small business users], and started instead developing for some other user base with lower standards]) such as android and windows phone [which have GUIs that look like they were developed for mentally stunted kids... think sponge bob meets interface/GUI development).

So as a general question, why are software interface designers getting in the way? Why are they severely impeding the ability of those using the software? Why is software that was developed years and years ago much more functional (in terms of user features [not referring to security aspects])?

I use Chrookmarks for Chrome as my bookmarks manager. You can set it to order alphabetically or by date. Then it will do all the work for you. You don't have to go through 100 folders. There's a picture of how it all will look at the link below.

To download a chrome extension, all you need is the Opera Extension called Download Chrome Extension, or Extension Source Viewer.

And I'm still using with Chrookmarks the Opera extension Add Bookmark, https://addons.opera.com/en/extensions/details/add-bookmark/?display=en, which lets you place the bookmark right where you want to, when you take it, in the bookmark tree, as part of one action.

There's no such option in Opera 26 for Mac.

This is the Windows forum, you may have more lucky if you ask in the Mac forum.

I was looking for the same, but It seems that You can´t sort the bookmarks, at least I dind´t find It or How to do that.
I was happy that the bookmarks returned, but they forget to implement that basic feature, sort Your Bookmarks by name! Now I have maybe 100 bookmarks sort randomly...

EDIT:

I found It!

You can actually sort the folders and their content, just go to Bookmark Menu, in the top left Opera Icon, It will show You the option to Sort alphabetically when You right click the Folder that You want to sort.
