This is a simple plugin for ExcessBaggage which should make maintaining bag space for rogues, warriors and mages slightly easier.
Using the Options panel you can select whether you want food and/or water to be considered when ExcessBaggage tries to automatically make 1 space.
So if you were a rogue then you would set this to destroy water, so when your bags are full and their are no cheaper greys than the water this will destroy the water.
