Same, although I don’t think I ever actually unlocked the exhibition room in New Leaf, let alone use it, lol.You're not the only one. If I'm given something by my villagers, I'd want to keep it for as long as I can, especially if it so happens to be a rare/unorderable item. Unfortunately, my storage is filled to the brim, so I either display it somewhere on my island, keep it in my pockets (which is annoying for me), or make a tough choice of selling them. I wish we had an exhibition room like in New Leaf so we didn't have to sell things.
