This app is generally a great tool for me. I second the request someone else made regarding more precise masking and that would be changing the preset brush sizes to a variable slide controlled brush size controller, so one can get into tight areas.
Another thing would help greatly: the ability to lock zoom so that one can paint the mask without the image constantly zooming in and out. Being able to pan while in zoom would help a lot.
For those who have difficulties using fingers to mask, I would suggest trying a brush stylus such as the Sensū Solo or even a regular rubber tipped stylus. It is much easier to paint with than a finger.
