This is one of the prettiest apps I've ever seen! Amazing interface look.
And it just worked w/o problems first time I tried it.
Firrst off I think it really needs user-customizable profiles. I think everyone here has some favourite switches and would like to tweak an option or two...
However, I like your simple design and minimalistic look very much and would hate to see it bloated and cluttered in any way. It would be great if you could keep this simple elegant feel while adding new options.
