What is the enhancement in mind? How should it look and feel?
Is it possible to have something like fuel for the helmets? So, you set whatever you want the default air supply to be for the helmet and once you run out the plugin looks in your inventory and if you have a fuel item (that's set in the config) instead of dying you lose the item. This fuel would give you a configurable amount of breathing air and once you run out the plugin would look and see if you had more fuel. Then once you run out of fuel you'd start drowning.

Please provide any additional information below.

Something like Sugar Cane for fuel (reeds to breath through!) would be best for default, I think. But if you could make it configurable that'd be nice.

This is on my long term to-do list.
