I think you've sold me. I can't wait to really sit down and dig into the demo tonight.

I had way more than $90 worth of headaches on my last iOS project keeping UI assets straight. I had no automated workflow; it was "do this in Photoshop then change the color manually for each one and then probably forget once or twice to export the correct resolution and tear my hair out wondering why it looks like crap."

I absolutely hated making minor iterations to the design, because I'd have to waste half an hour changing everything for a few pixels difference.

Thanks for the recommendation on this!
