Facebook is a great website, but it still misses some useful features. I wrote several applications to implement some of those features.
Content Search
Facebook lets you see the recently posted material, however once that material goes down in history, it is not easy to find it. I wrote Content Search application that lets you search for your photo albums, videos, events, etc by keywords.
Friends Tracker
Facebook tells you when you have a new friend, but it does not tell you when someone unfriends you. I wrote Friends Tracker application to help solve this problem. Every time you launch it, it compares the list of your friends that it stored last time you launched the application to your current list of friends and tells you who is new and who is no longer there. Once you look at the difference, you can reset them so that next time only new changes are reported.
