Everything is starting to work really nicely. The keyboard support works well. With the MX Keys mini, I used to have a lag problem when hitting function keys -- this is resolved.

There is one little problem that still exists, however. When in function keys mode, the volume up doesn't react and perform volume up with the function key depressed. The key does perform volume up, however, when the function key is not depressed. I am able to work around it but it is a weird little eccentricity.

App looks great though, really coming together now.
