Trash Button addon
As a concept, the Trash Button addon is very simple, but nonetheless extremely useful. I've personally encountered situations when my inventory was full of blocks and items I didn't need, without a way of getting rid of them. The trash button in the inventory will delete items you don't want in one click. It's already a thing in games like Stardew Valley, and there's no reason why it shouldn't exist in Minecraft.
