Because the description is too long for the Steam Workshop.

#1 Get yourself this mod for various mod support. #2 Take that as a guide to implement your own mod support.

I guess you can paint things with this mod

QualityBuilder doesn't use the minimum quality setting when replacing building material - it won't re-build to get a better quality. That being said, it can still restrict building to skilled builders only.

Don't use Better Coolers/Better Vents. It breaks replacing walls with doors. It only adds the same over-wall coolers anyway.

ED's Reverse Cycle Coolers changes the vanilla Cooler and re-writes a bunch of code so it's 100% not compatible with other mods.
