Added a highlight for the last parcels of a shift: once five or fewer are left to sort, every one of them shows through the racks and walls with the pulsing orange outline, wherever it is — on the floor, in the trolley or on the wrong shelf (the one in your hands isn't highlighted). The outline can be seen from anywhere in the hall: it's at full strength within 6 metres and dims further away, but never goes out.
Thanks for playing and for all your feedback! If you're enjoying the game, a review helps me a lot.
