i would love to see the forum post format changed to be a lot tighter than it is. for instance place the vote box and the picture on the left side of the title so that it doesn't take away so much from the screen real estate. i.e.

Vote Pic Title flag reply
content

as opposed to what it is right now:

title
Vote
content
picture
flag reply

maybe it's just me but i would love to see more comments fit on a single page than what we have right now.
