Hello, thank you for the suggestion, i'll consider adding a secondary constant upgradable tab for wbag (inventory).
Out of interest, what are most of the items you'd want to place in that storage ? (food items, taming items, cloths,milk cups...)
P.S.: For now, then first few rows in wbag (inventory) are constant/permanent. It can be upgraded by using the wbag item on a tamed female fapet (more detailed explanation is represented in story and help tab).
Cheers,
~NK
