Inventory .... both the party inventory and the camp inventory.
First of all...it is just an annoyance to have individual inventory when you magically can teleport everything around beetween the party members no matter where they are and when you do it. . Take a look at the inventory management of pathfinder kingmaker. There is a total number a party can carry, and else it is just organized in a single big stash with some different sort options. Every charakter has a personal equipment on top with his armor, weapons...
Suddenly there is no need for a magic box in camp to transfer things from anywhere in the world to it. THIS is realy unimmersive and should not be in the game at all. If there is a box, don´t make it the magic teleport box....
