I got heavily into the "Bookmarks menu", with subcategories for FAVORITE seed vendors, ASIAN seed vendors, Tomato seeds, GOOD seed vendors, OTHER seed vendors, Garden Links, Garden Other ... and some work stuff, too.
I keep a bunch of favorite links in my signature block here. Sometimes the fastest way to get somewhere is to go to ATP first, and then click in my sig block.
