Looks quite nice but still has some rough edges: - full screen doesn't work, at least here - lacking support for auto-grabbing in absolute mouse mode - unscaling (ctrl-alt-u) is lacking - window not resizable (except in broken full-screen mode) Will see if I find some time to look into this. Is this also working properly under Windows? Otherwise we probably can't deprecate SDL - or would have to provide a native Windows GUI. As we have a menu now, I would suggest to add some handy monitor commands there as well, like reset or powerdown.
