Problem: when you try to remove a bindle/travel sack/backpack, the extra slots it gave you need to be empty, even if there would be enough space in your "standard" inventory to move them around, forcing you to rearrange items by hand.
Solution: when trying to remove such equipment, IF there is enough free space in your inventory, you should be able to do so without having to manually move all the items yourself. Your inventory should sort itself, allowing for quick swapping of equipment.
I find it very annoying when most of my inventory is empty but there is something that overlaps with the "extra inventory space" preventing me from unequipping bindles or sacks without having to manually move it.
I know it's not a huge deal, but it happens very often to me and it's an easy enough feature to add. It would truly be a QoL improvement for me
