I think it would be advantageous to have a move up and down arrow on bags like quivers have.
The coding is already done just apply it to bags. I hate not being able to organize my large bags. I like to keep similar items together and unloading the whole bag wastes time.
I also think a sell multiple or buy multiple tab would save a lot of clicking time.
Just simple adjustements that won't affect game play other than make it slightly less tedious.
