I have alot of ideas:

You could make the Grenade spawn a second form of fuse powder which automatically detonates with delay and making small explosion somewhat like fireball

Day/Night cycle display stuff that glows , glows and vice versa
Clone Display: Clone gets the color of element (usefull if you use alot of clones)
Make C-6 explodes with fire too

C-0 by default it explodes yellowish fire , different ctype spawns different effect like with ctype of ln2 it would spawn ln2 or oil etc... depends of ctype (look it on lava)

color bomb like (red bomb , blue bomb etc...) so users can customize the color of its explosives
Napalm
Adv Sponge/sleeping BREAKable[meltable] clone (Like sponge but customizable like C-0 with ctype)
Acid should be blue or green and giving off blue/green fire
Neutron matter should have the effect like on maksprog mod
TNT is way too powerfull i mean we have nuke which makes alot of pressure i think Nuke is enough
BCLG (Breakable customizable laser gun that spawns either cold laser or hot laser depends on ctype instead using 2 variants)
Bomb Hull breaks easily melts somewhat you can contain there everything explosives even bombs , acid , thunder etc...
I think those Clone variants should be destroyable



Bugs:
Thermite doesn't spawn any lava

Yes C-Zero if it has ctype of Bflm it will create blue fire if its gona explode or spawns fuse powder when it got that ctype

I hate soap because it has a bug. When air comes to it, it crashes the whole game!

Ohhhh okay..

Great work me4502!
