Well by editing the source you can put new commands in. Like one mod has a life {l} command.

I thought you could program a display using the console.

Yes, pressing the ` key, the console appears. Currently, the commands I know are:

reset pressure

set type (element) (element)

set ctype (element) (element)

set life (element) (number)

set temp (element) (number)

set tmp (element) (number)


And heaps more, I can't remember them all.
