I don't know about anyone else but I always feel a little too limited in how many weapons I can bring along, especially anything that requires ammo, as it's 1 weapon that requires 2 slots to carry. So a Mod to gives some additional carry slots is my formal request, nothing too extreme, just another 2 or so, perhaps located at the lower back area.
Additionally perhaps a way to lock the innovatory cube in place so that I don't keep accidently grabbing/unequipping/dropping and loosing it, rendering me unable to access the inventory for the rest of the level.
