YES. I should have mentioned Add Bookmark too. I use it, and consider it very valuable.
Now this extension does help on adding bookmarks. Without it, you have to drag from the Speed Dial (a link/thumbnail) to the Personal Bookmarks bar (to create a bookmark), or the icon on the left of the address bar to the Personal bookmarks bar. But Add Bookmarks makes it a lot easier. Since you're not showing the bookmarks bar, this was a problem. A thought though, because I don't show the bookmarks bar either. I prefer the minimalist look. And why waste the browser real estate with the bar. You can toggle the bookmarks bar to show (well, . . . it's close to a toggle :)) when you need it, by just going Alt P, and then putting the dot in show the bookmark bar. Do what you need to do with the bar. And then Alt P and take the dot out.
As to what Opera should do, they have so many priorities -- what to do first. They've been reprogramming from scratch with the new Browser engine, and have made a lot of progress. But I'm sure they have a lot on their plate. I just wanted to pass along some ideas that might help you right now.
