I don't know if davidc is already working on many features ( you actually did a lot of work, davidc! Thanks a lot!), but I decided to make this list. The majority of these are from GooFans, I think.
On GooFans we have this useful thing called "Unread posts". Maybe it's a good idea to have one in here.
P.S. And maybe adding graphical smileys
Feel free to post anything that you'll like to offer to davidc as an idea of imrovement for this site.
