This is just: wow. Perfection. Great idea, and I really hope Nelson sees this and makes this a thing in 4.x.
A few things I do want to point out:
Bottom right, the cargo pants slot. Nelson will also have to find a way (or you to make generators a different size or too much weight to carry in the pants. The current portable generator is 4x4 slots, and in real life that would be way too big to fit in your pants (even though it’s called portable).
It may be a bit too harsh, but I think there should be a little barrier that makes you unable to store for instance a fish inside your vest. Like, the vest should be limited to use for magazines, knives and other military related stuff. Carrying a fish around in your vest may be a bit f i s h y.
The backpacks could also have pockets, like I drew out here:
(bit ugly I know, yet it’ll do for now)
That’s all commentary I have. as I said, great idea, hope it gets implemented!
