What do you dislike about it? Specifically, what about it makes it "unusable" for bookmark management, and what UI changes would constitute an improvement? I strongly prefer it to the apparent alternative, which seems to be an HTML-native interface in a tab. In fact I think doing that to preferences (about:preferences) was a step in the wrong direction. Not only is the result rather ugly (IMHO), I'm constantly losing my preferences tab among my other tabs, whereas a separate window with a native UI has a single instance (more appropriate for preferences) and doesn't get commingled with web pages.
