Something else that I have had repeated requests for, and a feature that might fit in quite well with the Control Panel, is a Find User Feature. Right now, in order for me to get to a display of a user's profile, while armed only with a user's name, is to perform a Search by User to display the user's posts, and then to click on the user's link next to the post.
Many times I just want to be able to search for a particular user and be taken directly to that user's profile. There is, at this time, no direct way to do this. Consider it a "favorite users" feature for the Control Panel, to go along with "favorite threads" and "favorite forums." Just make it a small search box rather than a listing.
Which leads me to another issue. If we must enter our Control Panel to see whether our friends are online, wouldn't it be just as easy to eliminate the "Who's Online" link from the main displays and put it in the Control Panel? Same with the User List.
