BlingBox™ keyboard

[AlbertoGP]

I prefer a native app as well, but I also have the ability to do everything wirelessly in a browser as a web app. This means no code required at all on the PC/Mac/Linux side, just a lot of code on the keyboard side to do everything, but it certainly could be done this way.

That’s a good idea, this way you can skip implementing the serial protocol.
The UI could use the Keycap Color Explorer assets as a starting point.
