is there any chance you'd consider adding keyboard support for the controller selection?

It is possible, I would do this with a heads-up text to put some on the modifier keys and the rest where not more than two rows/columns overlap. All keyboard players know this problem since 8-bit and PC; n-key rollover became popular in 2014-ish and these keyboards could be connected to the Amiga with a supportive adapter. Or they already know some good setups.
