Well, i know the second one wont get attention but my first suggestion would be:
Range. make each device having more range, the range of now is kind of slow, and isnt that good
Nuclear Procedure. Being able to use a bomb that would destroy an entire city and leave it burning, maybe compatible with basements so the trapdoor wont break, but i just want a nuke mod tbh as there arent any, and no, radiation mods wont count as bunkers doesnt protect you from them, making it annoying.
