It could be really nice to be able to filter by some parameters, like rarity/use/anything else in the Quick Stock page, like we can in our shops and vaults. Now that I have tons of flowers in my inventory but also many items that I want to move to my shop I find it could be very useful!

am a fan of this idea! have been having the same issue with flowers during vesnali, and like being able to see items by category of rarity :) it would also help with sorting slots items and other game prizes.
