I already suggested a change here but then I found what I suppose is a bug or at least a strange behavior.
Talking about logistic slots, when you first open your inventory no slot is selected and displayed amount on slide is 0.
then you select a slot - it get highlighted and the set amount is displayed on slide.
if you clear a slot (right click) the selected slot will not change (previously selected slot will remain highlighted and slide will keep current value) - I consider this behavior correct.
but if you clear the currently selected slot, no slot will remain highlighted (correct - you cleared the selected one) but the slide will not revert to 0.
Closing/opening inventory resets the situation.
The same happens for both player logistic slots and requester chests.
