Items disappear behind long set list on narrower displays.
I am currently using a setup with three 4:3 screens.
On those screens the arena is scaled such that the item storage is at the very edge of the screen and it can get covered by a long set list. Then it's easy to miss that you have items left.
it could be fixed by moving the set list upwards a bit. Maybe make the list shorter by reducing the space between sets.
