I was surprised by many of the features in "Photoshop Touch for Phone". I've been using Photoshop since 1993, and own the CS5 Mastersuite.
When it comes to quick-n-dirty enhancements, I tend to hit Auto Tone, Auto Color, Highlights/shadows and then adjust Vibrance.
I would assume that this is a popular feature and processing power isn't an issue. If you could add Vibrance it would be awesome.
It would also be great if you could come up with a higher-tech version of highlights/shadows.
It would make the app so much more "Field Tweak" ready.
