Controller for iPad, ideas anyone?

[OneLittleFonzie]

Hello

After I made the Jupiter Controller (http://itunes.apple.com/us/app/super-jupiter-8v-programmer/id474438636?ls=1&mt=8), I'm working on a controller for the Mg Modular. This is a bit more work of course but it's going very well.
I would like to hear some ideas that could be incorporated.

Thanks for the input

Regards

Ron
