When I move URL's in the Bookmark Section from one folder to another, I have to be VERY precise with my mouse. I have to be very careful to go only horizontally with my mouse, which slow me down alot, especially if I'm moving several URL's. And working from a folder in a folder. If my mouse leave the folder window for 1 Milisec, it closes right away.
If you ask me, that not intuitive. Solution: Keep the displayed window open for a short period of time instead of instantly closing it when the mouse moves in another folder. That would feel alot more natural.
