Suit program block
An idea would be to add a programmable block funtion to the suit itself, it cannot access blocks, but instead the players health,hydrogen, speed gps position etc. It should be able to use the suits onboard antenna to transmit and recieve messages just like the normal antennas can.
it should also be able to detect certain buttons on the keyboard ( or some other solution for interactability )
this would allow for useful things like garage openers, distress signals that calls an emergency suply pod to your location, and also status screens that monitor the position and status of your allies if they set up their suits to transmit their health and stuff.
with clever programming i think this could be a really interesting addition!
