I really like your slick interface with the sliding effects and all that, but the one functionality I was hoping for isn't in the plugin. When I search for and find a user and click that user, it just pops up the built in user_edit.php interface, which doesn't show me all the fancy meta data I was looking for. The only way to see non-standard meta data for a user is to try to edit keys one by one.
Are you planning on developing your own user data display page that lists/shows all meta fields and values? It doesn't have to be pretty, just make it so I can see the values and maybe click to edit them... but really I just need to see the data. That's something I would definitely fund with a donation.
