MyAudiosurf would be the only laucher I used if it included Screen Tilt and all the other WM copydata bonus features.
Also, while I'm at it, one other request: could you either release a configuration client that I can launch without have AS autostart (i know I can change that in the options, but I like it autostarting), or a little flag in the shortcut line (like MyAudiosurf.exe -nostart, or whatever) so I can change settings without having to quickly juggle over to the steam launcher window.
