Suggested this a year or 2 ago, but thought I would bring it up again...
Ingredients bags can be a pain to sort out. The search option is great, but it would be so much better if there was an up/down arrow on them so we could move certain ingredient types so they were grouped.
I would recommend a similar mechanic to the way quivers work, so that if one were to add, for example, a new challenge material type, one might select that stack then up-arrow it towards the other challenge ingredients in the list. This would allow players to sort their bags however they liked, without emptying their bags and reintroducing them to that same bag item by item.
