Inventory Suggestion?

[Berteaux_Braumegain]

But each equipment are different since they all have a durability, spiritbond, dye ID and glamour ID. You can't stack 10 "Anemos hat" because the game still needs to store 10 different durability, 10 different dye, etc.

For the lockbox opening UI specifically, the simplest addition would be a "Throw away" button.

This is a fair point. An option to discard/immediately sell an item upon receiving it would be appreciated. Or a mass discard/sell option.
