Sorry for so long waiting this feature!
Our old API is held back implementation of any new features, but as you may have seen in recent blog post I rewritten it from ground up.
So now it's possible to make changes and add new features. And first is most requested one, manual reorder of bookmarks.
To enable this sort mode, click on sorting combobox and select "Manual".
If you have any issues with it, please share them in the comments!
Expect more polished version (with fancy animations) of this feature in next major update.
Support for this mode in mobile apps will be added soon (just view for the moment).
By the way about next major update. I decided to hold work on it, and just implement features/fix bugs in current version first.
This way I can iterate faster and you receive new updates more often.
Sorry guys about long list of awaiting features! I promise updates will arrive more frequently!
