The one thing that might make it even easier to use might be a 'zoom' option in the desktop version of the Form Designer, so that you could zoom into the form when positioning your buttons etc. (A simple 2:1 would be more than enough).
It can be pretty fiddly at the moment and when working on PC monitors that are running at high resolution the little 320 x 240 form seems tiny in the middle of the screen, especially when I'm cramming an un-feasibly large number of controls onto one form....
