New for Qt, moving the mouse over one of the slots in the paperdoll inventory subset and letting it pause there will use Qt's tool tip mechanism to give a description of the item under the pointer, if there is one, or of what the slot would contain when there isn't. So "e - uncursed leather gloves (being worn)" or "no gloves" when the pointer is over the glove slot. If you do something with the keyboard to make the paperdoll change while the mouse is still hovering, you'll need to move the pointer slightly to have Qt recheck for tool tip at that spot. It may be feasible to force an immediate update, but I'm satisfied with how it's working. Interestingly, you can move pointer and hover while yn_function() has asked you to pick an inventory item and is waiting for an answer. Mostly useful for Take-off/Remove or #adjust.
