FS-UAE has a very advanced interface that not looks like the real GUI that an emulator machine like the Minimig ECS/AGA done in FPGAs, or an Amiga could do.
But aesthetically its very pleasing to the eyes, I understand what you are saying, and while I think would be best to use it, it doesnt fits very well in my idea because its a very futuristic interface, and I would like to see something more retro like Commodore did so well, while not loosing at all the flexibility of emulators running under Windows.
