What would be a cool facebook application?

[Phillip B]

I create applications and I would like to see what you guys think would be a cool facebook application.

[logon2]

An application than blocks annoying invitations to stupid applications that are completely degenerate.

[Searcher]

An application that allows you to see who enters your profile.

That would be interesting.

Hope this helps

An application that will allow you to change the background and other things on your profile. Kind of like myspace when you can have a background color besides white. I love facebook, but i would love it more if you could customize it a little bit more. hope that helps, and you can do that!!~
