Loving FriendFeed Apps and the greasemonkey scripts that are being produced. If you are a FriendFeed user this site is a must. I am currently using:

• “Tabs – add custom FriendFeed tabs and never leave the site again!”
• “Show Domains – displays the domain name of all shared links”
• “TinyURL Resolver – enables one-click instant inline preview of TinyURL links that show up on FriendFeed”

They also have other scripts as well. If you are not trying greasemonkey scripts for FriendFeed I highly recommend that you try them out. Link
