Found it weird that the inventory system is just a bunch of individual bags thrown onto the character. Even more weird once you get to the backpack stage and you're carrying around 4 entire backpacks which leaves me with the mental image of someone trying to bring all the grocery bags in on a single trip, or that trope of a boyfriend following his girlfriend shopping and holding a billion clothing bags.
Thought of a neat idea: singular modular backpack with slots for customizations.
The first slot in your bag menu is a primary backpack slot. So a large reed basket, a linen sack, mining bag, leather backpack, and sturdy leather backpack.
Second slot fits something onto the top end of your backpack, the third slot in the bottom left, and the fourth slot in the bottom right.
Customizations can include a torch holder/lantern, a sleeping bag, pouches for additional inventory, ect. Each customization visually changes the backpack, and is tied to the backpack so placing it down keeps the customizations with it.
The total size of the main backpack could be most of the inventory space currently granted by a full row of the same tier of bags, with the rest being filled out by 1-2 pouch additions. So by equipping a backpack and a couple pouches you retain the same inventory space you'd get now plus 1 additional slot for customization. Or you could ignore pouches all together and still retain about 70-80% of your normal capacity while getting several slots to add things.
Could even further this idea by limiting the customizations and the amount of them to the backpack tier. So Reed Baskets get nothing, Linen Sacks get 1 slot, Leather 2, and Sturdy Leather unlocks all 3 slots.
