Needs more features – iTag Graffiti Review

This is a fun app to play around with but it is lacking some important features... There's no "undo" or zoom. Both are very useful in a digital art mobile app. I like the dripping and splatter effects but the opacity slider doesn't really change the opacity. It only makes the color lighter. Also, in this version when I try saving images on my iPhone 6 Plus, it only saves a small corner of the art not the whole image.
