I have had this app on multiple devices for over 4 years. I have loved it so much, it was so simple and easy to use. I am commissioned as a digital artist often and this was my software of choice. Today I opened the app to finish a project I've put 7 hours into and found that the update has changed almost everything about the experience. Removed the "undo/redo" arrows? No more easy short cuts to adjust brush size, you have to go into options now every time. Please put those features back.
