I would like to add some custom buttons.
1. Button that starts autolevel
2. Button that turns the CASE_LIGHTS_PIN on
3. Button that executes a particular gcode file (not just recently seleced)
with #3 I could just write the gcode to execute whatever for #1 and #2
I have looked at the long list of options at top of ui.h but I just don't see how to do it.
