Organize your IE7 Favorites
Favorites Box lets you add extra attributes to your bookmarks to make them easier to find and organize. Add comments, categories, tags, or login information or even set up a reminders. This one's free to try, but sets you back $19.95 if you want to keep it.
Favorites Finder is a free extension that adds keyword functionality to your bookmarked sites so you can access them in just a couple of keystrokes. Just type a few letters of the site you're looking for and Favorites Finder will search your bookmarks and find all the matches, including whatever's in your folders.
Power Favorites is a slick little extension that merges bookmarks from IE, Opera, and Firefox, then syncs them across multiples computers. You can annotate each bookmark with notes and tags, then view them by tag list or tag clouds. (Tag clouds? Are you listening, Foxmarks?) Power Favorites has a 30-day free trial, then it's $19.95.
When you finally decide to winnow down that super-long list of Favorites you've accumulated over the past two years, it's a pain to have to check each bookmark to make sure the site still exists. Use the free tool Favorites Inspector instead. It will plow through your whole list for you and alert you to any "404 error" pages so you can delete those Favorites instead of filing them.
