I’m with Greg Houston. Bug fixes ( failing this then everyone should get paid for being beta testers on newly released software) and fully dockable interface.
Like Greg says just because it’s all dockable doesn’t mean it has to be all glued together. I’ve got plenty of software that has dockable interfaces and you get the best of both worlds.
I’ve got one piece of software that is so adjustable it brings a happy tear to my eye. Steinberg do seem to be stuck in the stone age when it comes to interface customisation. I’d be embarrassed myself.
