I'd love to see a global chat that we can all talk on regardless of leagues, its hard to connect with other players when you have to be on a league chat and almost everyone has multiple teams.

Or at least a "Who's On" window/box

As long as the global chat window is not always open by default.

It's bad enough having to close the league chat window every time you enter that league, and not even being able to move or resize it.
