Hello!
If there is already a suggestion about this/like this feel free to delete this post or let me know

I was creating a trade just for food items, and I had to scroll through all my decors and amusement items to get to each carcass, so I had the idea that when you're creating a trade there could be tabs or something saying 'food' or 'amusement' or 'decoration' etc. next to 'Items:' (sort of like in hoards) and when you click it the items in the scroll box would only be the ones that belong in the category you selected.

I'm bad at explaining things so if you have questions feel free to ask, and if you have any additional suggestions for this please let me know
