In case you've all fallen in love with SafariStand like Laurie and I have, you might be interested to know it's been updated to 2.0b6.
For those unfamiliar with this fantastic Safari add-on: it's a plugin that adds a lot of extra functionality to Safari such as a sidebar with OmniWeb
-like thumbnail tabs, (pictured) address bar shortcuts, a "bookmark shelf," syntax coloring when viewing page sources, forcing new windows to open in tabs and one of my personal favorites: bookmark properties such as color labels, categories, comments and ratings.
