+1 For no. 4 ... everything else sound horrible
I actually like 1-4 and 6.
There should be separate containers at camp for organization.
Wares, Food/Supplies, Quest Items, Crafting Items, Equipment, Texts, Misc., etc.
Tabs like the inventory has might work as well, however.
Having a character to sell things would be convenient.
Though 25% is too much, and 10% might be better.
Having characters to automate cooking and other crafting in bulk would be good.
