Sorry, this might be one of my crazy ideas, but what about re-designing PHOT? Since people keep asking about gamma rays, infra-red, etc, that kind of light, why not create a PHOT section in the menu? One line completely dedicated to PHOT just to straighten up things when we get new "light" elements. I don't really know any programming at all, so I won't be able to make a mod :(. But yes, a PHOT menu would add more realism to the game! I've been thinking about some physics work here, but I think it's a bit (maybe extremely) too hard to program ;).
but i think instead of a seperate menu in the menus, I think you should just drag the curser over the PHOT in the radioactives section and another menu pops up above PHOT with all 7 different types of radiation. I think this would be the most logical thing to do.
