Amazing that it works so well, nice!

However I can’t help thinking usability improvements are urgent. The key one being how you need to bring up the menu with a 2 finger slide up, and then click again on the right button to get the list of apps, which is not even user friendly. Then, clicking on the top right window button to close the app, which you seemed to have difficulties to click on (with good reasons).

Finally you drag and drop a lot, can’t you click on the music file directly without opening the app in parallel?
