True! it is at least a starting point for experimentation though… maybe someone else with the time on their hands will carry the baton the rest of the way
You could consider writing a substitute class that inherits Arduboy2Base (and possibly the Print class), like the Arduboy2 class does. The Arduboy2 class itself is just the text functions, so you could use it as an example/base to write your own text handling.
…seems like at least one person does!
