What I am suggesting is for when you are offering or creating a trade, that if you have multiple of one type of item, say you have 5 Meerkat Skulls, that it would be collapsable and would only show up as one checkbox with a little arrow beside it, and when you clicked the little arrow it would "open" and you would have the full checkbox list of all the individual Meerkat Skulls, and then if you clicked the little arrow again it would "close" and you would only see the one. It could say how many of the item you have instead of uses, etc.

An example would kinda be like this: [] means checkbox

Closed:



[] Medium Meat Chunk (4 uses) (rots in 9 days)

[] Meerkat Carcass (1 use) (rots in 6 days)

[] ^ Meerkat Skull (5 Items)

[] Mist (10 uses)



Open:



[] Medium Meat Chunk (4 uses) (rots in 9 days)

[] Meerkat Carcass (1 use) (rots in 6 days)

[] -> Meerkat Skull (5 Items)

   [] Meerkat Skull (3 uses)

   [] Meerkat Skull (1 use)

   [] Meerkat Skull (3 uses)

   [] Meerkat Skull (3 uses)

   [] Meerkat Skull (2 uses) 

[] Mist (10 uses)

Maybe if you were to check the closed item checkbox it would select all of the items inside of it? You would still be able to open it up and select which of the individual items you wanted to offer/sell.

I totally understand that the coding might be difficult and unreasonable, and if so, feel free to say that it's just not something you can do, and I definitely won't feel bad. I just get sick of having to scroll through so many duplicate items i don't want to sell trying to pick out the ones I do want to sell.

Another suggestion is to have it as easily organizable as our hoards are currently, with categories such as food, decorations, toys, etc.
