Simple suggestion (well maybe not codewise) but i would like to be able to change my titan key name. Also, could you possibly put the account name on the account management page?
Changing the Key username is probably not going to happen. If you're unhappy with your name, you can change your display name individually on each site (well, on CIT and Faces, but that feature is going to work it's way into the Planner as well).
As for putting the account name on the Manage page - yeah, that's a pretty obvious bit of information we missed!
