Just got a new MacBook Pro and was finally able to test out an M1 native version. 

There aren't any new features other than that and a snazzy new startup screen that I hand painted myself - thank you very much. Aside from that there is a new core data entry for tracking FCs, but I haven't made a visual representation for them yet, but they are getting saved and will be displayed in the future.

The M1 version runs a lot better than the emulated intel version on M1 machines and if you got Pro displays, it play at a smooth 120 fps. I didn't do any tweaks to improve performance on the M1, I don't know what I can do - SceneKit doesn't take advantage of multi-cores.

fyi, I did intend to make separate M1/Intel versions but the file size was pretty much the same for both so I saw no benefit for it.
