I've been looking all over for some way to make iChat AV video chat windows float. Chax does that. It's awesome.

Also lets you customize the buddy list, add dock notifications of background chat invites, gets rid of the "do you want to start this chat?" message, and otherwise lets you customize stuff in iChat to your liking.

Only criticism: No real documentation. A simple read-me would do the trick.

Great little program, and the price (donationware) is right! This is a must-have iChat utility!
