When I accidentally press CTRL + Q
You can change or unassign that shortcut in settings. In fact, I don't think its a default. The standard exit command is Ctrl+Shift+X.
Sometimes when I paste a link, Opera removes the colon from http:// so the link won't work!
I have honestly never had that happen or ever heard of that happening.
I can't seem to get rid of the My Folders folder or move all my folders to the directory that My Folders folder is in.
Yeah, that ones annoying. If you like the extensions sidebar you can give V7 bookmarks a try. It makes navigating bookmarks a lot smoother.
If Opera could please consider rectifying these issues in future, I would be very grateful!
