I suggest adding dedicated gear slots (armor, weapon, shield, ammo) and various backpacks.
As the title say, I suggest mainly for dedicated gear slots.
But also I think various "backpacks" would be a nice addition.
For example the basic backpack that add more slots to the inventory. Maybe another that adds less slots but more weight (carry capacity), an arrow quiver, a pouch for food and healing items, etc.
I also want to use this chance to thank you for such a good and fun game! Keep the nice work!
