Sneakture 2.0...
The information overload is HERE in the GGPOtest branch!
In addition to the moderately useful wireless indication, [h3]Skullgirls now displays the most important information about your connection:[/h3] [h2]The "jitter" (variance in ping time) between you and other players.[/h2]

Usually more important than ping time, the jitter in packet transmission times is what causes large rollbacks and other undesirable effects.
This information is also displayed in Quick Match, and the game will color connections with bad jitter yellow or red the same way it colors connections with high ping.
The ping time and jitter info is updated at half-second intervals and is always displayed. The top line of lobby boxes now switches between location and lobby-relevant info like win count.
UPDATED 5/12, 1AM:
- Fixed wrong display of 2000+ jitter after playing a lobby game. :^P
- Fixed display of "" in lobbies when returning to the lobby after a game.
Uh, but...I had to rewrite a lot of things to get this to work, so if you notice anything weird like desyncs, please tell me. :^)
