People often complain about all the empty stalls and I can not help but wonder if one of the reasons is the wast of time checking them.
Would it be somewhat easy to change the stall graphic to have a closed sign hang from it or one spawn just in front of it. Maybe the same way that the stall shows different little graphics depending on how many items are in it.
Looking at you Marp I bet you could whip it out in 20 minutes. but if you are still working on the hobby horse animation by all means finish that first.
