Potential useful art tool but ad services create lag

Love the air brush and the handling of some tools but the workflow is hindered when using multiple brushes the ad is so easy to trigger and kicks you right into safari also it is animated and distracting. Cant wait for developers to hide these in the background or zoomed out so it still gets them paid. But it isnt as useful as some of the other free or paid apos because of these faults. But it like abother review says requires constant zoom in zoom out which defeats the greatness of the tracking of the tools zoomed in tracking for drawing.
