Was just thinking I would use the dashboard a bit more if:

# When hovering the 'More' links be able to get information (specially if there's nothing more to see, get a tooltip saying 'no more groups/lists...' or '5 more groups/messages...')

# Option to set the quantity of links for each widget box

# Able to add other things like hot bookmarks, one friends bookmarks... any custom Diigo feed

# Keep widget collapsed/expanded positions between page reload

# Have a feed of the dashboard page

# A text box we can often update for shouts, quotations... like facebooks wall (?)
