Fairly simple and would work exactly as Life Gradient Display.
Shift + 1 is for Life Gradient
I would believe that
Shift + 2 would be for TMP Gradient
It would add an interesting way to view for example: FUSE counting down, VIBR charge*, BMTL count-down (as well as when it spreads through metl), GLOW, GEL*, BHOL/WHOL intensity, EXOT*, WIFI channel*, PRTI/PRTO channel, TRON color, MERC build up, etc. (* already shown in default display)
A few discussions were made about it a few years ago and it was said to have possibly been added back (or in a debug mode).
I also would like to see tmp2 added in debug mode.
Or velocity gradients?
That was a suggestion.
