Tired of not having room for anything you want in your armor? This 32x32 armor combined with the Lejv Fusion Reactor makes a must have lategame item, at a really high cost.
Robot follower increase would be awesome. If you could get a way to deploy robots faster that'd be cool too. Better exoskeletons would be great, rather than having 12 regular ones lol. And better personal roboports. 10 per roboport is a little small. I want to be able to deploy hundreds of robots at a time. And maybe a teleportation module?
This one could be a stretch, but maybe add multiple modules like a flight stabilizer, rocket pack and landing gear. And when you have all 3 on you can fly so you can go through your factory without bumping into things and go over water
