minecraft version: 1.12.2
omt version: 3.1.12-378

Currently the Disposable Item turret can fire any item you list in the configs under: stringAmmoAllowList
While this is great, it seems odd to me that cobblestone does the same damage as woodplanks, to say nothing of the variety of possible ammo selection.
So my suggestion is to change this:

    S:stringAmmoAllowList <
        minecraft:cobblestone
        minecraft:woodplanks
     >

Into this:

    S:stringAmmoAllowList <
        minecraft:cobblestone,3
        minecraft:woodplanks,1
     >

Where the number after the comma is the baseDamage dealt when shooting that ammo. This would allow for a more thorough customization of the turret's damage, and also allow for fun and silly additions like shooting 0 damage snowballs or slimeballs.

Sounds good, gonna add that in 3.2.0
