I'm OK with that. It seems stable enough on both GTK and MSW. If it's
required to build on MAC, then it seems like a fairly straight forward
decision. As wxAUI matures we even could start to enable some of the
more esoteric features like dockable windows and movable toolbars. Any
time we can remove code between #ifdef/#else/#endif suits me.
