I got addicted to left-pane treeview bookmarks waaay back in my Opera days, imported into FF, still waiting on Chrome (sheesh). But at this point I doubt it would make a difference since the performance advantage has been pretty much erased. FF is fine -- what is Chrome's real advantage these days? Honest question...

And there's still not even a decent extension that does it, which seems really odd to me. Anyone know of one (left pane bookmarks that is)?
