Personally i like to keep my inventory clean. All my Arrows in one Pouch, my Potions and Scrolls in another...
The premade ones for Camp, Keys and Alchemy are already great, but i want MORE. Give me a way to buy different Bags and add some settings to them.
Let me rename my Pouches, so i know which one contains what.
Bonus points if we get some form of "Marker" too, like the "mark as wares", just for different colors or icons. Auto-Sorting would be neat too, an option to automatically put potions into the pouch.
