It would be nice if there was an option that you could enabled/disable the ability of the contact list to "stick" to the edges of your screen if you drag the Contact List window within X-pixels of any of the edges.

I like having the Contact List window flush against the top-right corner of the screen. Manually clicking+dragging to get it flush can be a little tricky. If the Contact List window was clicked+dragged within X-pixels of any of the edges it would "stick" itself against the edge. I guess I can only describe the behavior as behaving like Winamp 2.x did (maybe it still does).

I'd appreciate that, too. That behaviour is called "Snap to screen borders".
