I've been working on this update for quite a while. First the issue was scope creep - I kept adding in new features that popped into my head. The second issue was testing all of this again. I refactored most of the code (again), which in addition to all of the new features, created bunch of new bugs to squash. I also battled memory issues - CircuitPython is not the most efficient, and the RP2040 does not have much "oomph". Thankfully, a majority of these problems were solved by just changing the way that scales are generated - creating them all at once made for a very large list of lists which is not very RAM friendly. Now, it only generates them when selected.
