Well to start with, I think most of us will like to get an Update of Style XP as it doesn't work with WinXP SP2.
After that you should give us loads of StyleXP themes. Of course you can provide them, cutting on WMP Skins.
Firefox 1.0 PR should be provided, as Opera doesn't support GMail. In fact GMail doesn't support Opera.
Maybe you can do with some cracks. Heh! Just kiddin!
Ahh, yes....The latest Winamp Update 5.06 and some cool AVS Presets. You've never provided them, I think.
At the moment I can only think of these. If I can get something else I'd post l8er.
