Is your feature request related to a problem? Please describe.
No

Describe the solution you'd like
With such a keypad, you could put various functions on physical keys, but without taking up too many GPIOs and space.

BTW: If you do something right once, you have the work forever. :D

Hi, thank you for the feature request!

Sadly, I don't think I want to include that in this plugin, I would have to change to much of the button control logic to support a keyboard matrix 😅
I think it would make sense to create a new plugin for this purpose!

Cheers,
Sam
