To be honest, I feel like in your minimalist efforts you have created an easy-to-draw-with app, but not necessarily one that's easy to use. The grabber should take you to something akin to an action sheet (no real minimalism inherent in that - design your own) and should have the save option inside there, instead of two different functions (one unintuitive without reading a description of the app, or you telling me on an internet forum).<p>Beyond that, I like the ease of drawing and the clean look of the app.
