Please bring back "Unsorted Bookmarks"! They were extremely helpful in organizing my Bookmarks. "Unsorted Bookmarks" was one of the reasons I chose Opera Browser and abandoned Google Chrome, because Google Chrome don't offer "Unsorted Bookmarks".

You then still have to designate saving into that folder and that's the problem. With Unsorted, you just slammed a heart button and that was it. Firefox had the same thing and i loved it.
