I'm not sure how long this has been a thing, but I love that IR now has it's own Robotic Parts category in the VAB/SPH. I was wondering how to do that with other mods/parts. It doesn't seem to be cfg related, because all the IR parts have the Utility category set there. Speaking of which, is there a reason to have duplicates in the Utility, now that there is Robotics Parts? Anyway, back to my question, how does one create own category like that? Also, how to add parts to it, because "category = Robotic Parts" didn't work (I'm no modder, all I can do is mess around with cfgs). I know I can use stuff like Filter Extensions, but I'm curious how this has been done. Even a link would be appreciated.
