When sending transfers of tons of items, selecting items for trade/raffle, creating nesting materials, etc. If there is a time where you need to select multiple items, lions, etc, it would be GREAT to not have to click through every. single. GD. box. A drop-down option to sort (like what is available in your hoard) would be great for this.
Especially when I'm creating nesting material; makes me feel like I'm playing Cookie Clicker or something.
