plot file(s) with push button(s) ?

[snug11]

hi all,
im asking for a possible (firmware) extension: there are a few unused gpios on the esp32...could them be used to start different plot files by pushing buttons (internal pullup on/gnd) with ?

for example:
gpio32/button1 = plot file "xxx.gcode"
gpio33/button2 = plot file "yyy.gcode"
(for best, pin assignment in ui under "sd-files area", beneath each loaded file)

that would be absolute easy to let guests (on a faire) start plotting different preloaded grahics without the needing of a second device (laptop, smartphone...)

...that would be great ! :-)

with kind regards from germany
