hello, i was tinking that could be useful to hardware monitor some signals from lakka using gpio (free lines) connector. i’m not linux expert and i dont know if this is a not feasable feature, hard to implement or really easy. but i think could be useful to have some output signals, connected to leds showing for example: 1)wifi/ethernet connection on/off 2)bluetooth connection on/off 3)player 1 controller connected(and recognized)/not connected 4)player 2 controller connected(and recognized)/not connected 5)retroarch service enabled/disabled 6)ssh connection estabilished/off
and some input like a reboot button shutdown button
when creating some nice case for retro machine would be nice to have some leds on front panel showing some activity 
just an idea…
