This is the win7 menu button for gnomenu. I think that it's necessary to have a win7 theme, because the principal objective of the project in the beginning (VistaMenu) was to emulate the windows vista menu and make more simple the transicion for windows users. So, if the default package have the xp and vista theme, i think it's necessary also the windows 7 theme.
Because that, i'm working now in a win7 theme, menu, button and icons. We must be original in themes design, but we can't forget the first objective of this project.
