What if the mods make like a sections? Example: Fish Sections.. Example: Armor Section Example: Wood Section Example: Weapon Section Example: Books section....
I don't think anyone would add that because that basically makes the less of an adventure and armor selection is similar to area teleport to a random shop so that would mean peoples money would be wasted.
I mean... it's not hard to check the vendors for the items you want? :<
It would require the payvault item to be completely reworked, as well as the code and method of MTD, so I'd be against this. There's no real reason to change it for now.
