I hope you can put some resources in fixing the Mac app, as it seems rather broken in many things:
- The brush sorting is very wonky, it probably should look like the iPad version, but it is all jumbled.
- The Gradient map UI is broken, see screenshot
- Having the color picker window open slows down the app, especially on tool switching, see the screen recording I made
- The text in the brushes overview is quite blurry
Please give it some love, as it is not really useable for me now. I know iPad is your main focus, but I believe the Mac app has a lot of potential that is wasted. Improving the things mentioned, plus a full screen mode and customizable shortcuts would make it a very good app indeed.
