Could you change the wording to avoid referring to ammo packs as "tanks"? In Super Metroid, I think of "tanks" as referring to Energy Tanks and Reserve Tanks exclusively.

Will admit that possibility didn't occur to me, but I've updated the public-facing text (admittedly, 'tank' got thrown in the identifiers largely from when I was still looking at supporting modifying energy tanks as well).

Can you update the other identifiers too, not only the public-facing ones?

And then let's put the UI controls in a card inside of the Item Pool collapsible (rather than being its own "Ammo Size" collapsible directly under the Item Progression modal).
