Let people play ZiteFight inside Facebook.

Let users tag photos or put them in categories so that on the vote page, you can filter the photos in fights so you don't get things like a person vs. a cake.

Allow users that upload fighter photos to get a widget with a fighter's photo, record and rank that updates as users vote on that fighter on ZiteFight. Users could copy and paste HTML for this widget into other sites.

Let users add fighter photos to ZiteFight by pulling their photos from Flickr and Photobucket accounts in addition to uploads.

On the public fighter profile pages, users would be able to enter comments about a fighter.

This leaderboard would show which fighters have made the biggest gains in rank over a period of time.

This leaderboard would show the top fighters by winning percentage that don't yet have enough votes to make it into the standard leaderboard.

This leaderboard would rank fighters based on their total number of wins all time instead of winning percentage.

Users would be able to "fan" a fighter. Fans of fighters would see their favorite fighters on their user profile page and would be able to see when a fighter that they've become a fan of has increased in rank, received a comment or otherwise changed.

Users would have a profile page with an avatar photo, a short bio and links to their blogs/other sites. The profile page would also provide a place for various additional widgets such as a listing of that user's fighters, fighters they've become fans of or recent votes.

Allow users to login to the site and create accounts using OpenIDs.

Provide a search box for finding users and fighters by username or nickname.

On fighter pages, show information about how the fighter's rank has gone up or down over the past several days. This could be done in the form of a small chart or even a sparkline on the fighter profile page. Comments/thoughts on how to do it are very welcome.
