How to change the Bookmarks appearance in Safari?

Hey all, since I've switched (and that's a while ago), I stuck to Firefox, but since Safari 5 is out, I like that much better. The only downside: There seems to be no way to change the appearance of the bookmarks in the bookmarks bar, its always plain-text. What I'd like to have available would be either *colored* bookmarks (tag-like) or just the website icon instead of the text (as in Firefox i.e.). I've neither found an addon, a trick nor even anybody who seems to be disturbed by that as I am Or do I just oversee something very simple? Would appreciate your answers, Cheers
