To make the suggestion very short:
Make stacking trinkets/consumables/etc. (harps for X/day, bandage rolls for X charges / use) stack their usages per day / charges when lumped into one stack, or anything that'd result in similar example:
Dove harp. A single one gives 5/day uses of cure serious wounds, so, a stack of, let's say, 12 dove harps would have 60/day uses of cure serious wounds, from a single stack, without needing to unstack and manage them.
Similarly with olmnar harps. 1/day use of mass haste per harp, so a stack of 10 would be a stack with 10/day uses of mass haste, for example.
And bandage rolls, 10 charges, 1/use charge for cure light wounds i believe, so a stack of 20 would have 200 charges p much.
