One of the big features I like in Firefox is being able to keep the bookmarks sidebar always open. As far as I can tell, this is not possible in Safari 4.0. Anyone have any thoughts on how to make this work in Safari? This is a dealbreaker for me, although I am enjoying Shiretoko, Minefield, Firefox 3.1 whatever you want to call it, I really like some of the new Safari 4.0 features. Thoughts?
