I think this is super cool and intend to donate because I love the love and thought you’ve put into this. With that said, did you consider using something like an Elgato Stream Deck programmable control pad?

Thank you for the kind words. I did orginally consider using a programmable stream deck, but quickly realized that it would not be sufficient. My requirements were:

1) Over 100 symbols immediately accessible

2) Single-hand use

3) Small size

The elgato stream deck meets some of these requirements, but it would not have been possible to support the amount of symbols I wanted.
