Options to change the location of items on your person, per-class.

As someone who has played a lot of Bonelab, I'm used to ammo being on my left hip, and I find it hard to change my muscle memory to reach for the front of my torso when going for a reload. If it were possible to change where the ammo pouch was located it would be incredibly beneficial.

Similarly, the ability to change where your weapons are, such as putting your sniper over your right shoulder and moving your gadget to your side would be nice, however I wouldn't want to change where other guns are such as my assault rifle, so ideally this would be adjustable independently for each class instead of a global setting.

For exact locations of items I would suggest these slots that can have whatever items in your loadout placed into (with their default item in brackets):
Left Hip (Empty)
Right Hip (Pistol)
Torso (Primary)
Grenade Strap (Grenade)
Ammo Strap (Ammo)
Left Shoulder (Gadget #1)
Right Shoulder (Gadget #2)
Lower Back (Empty)
