A Fun feature to add could be possibly power bills or brightness requests from customers, ie. customers complain store is too dark. Or different lights are more efficient for bills or brighter just anything to make the option to buy lights actually impactful, currently i have never bought them.
Another idea is different tiers of electronics that have greater efficiency as well, ie. starter industrial fridges smaller and less efficient and different models larger and more efficient?
Further, I see on roadmaps that there is something renovation like coming, which I’m hoping includes abilities to install and or delete internal walls.
Also maybe have actual use of toilets by customers/ maybe needs to expand facilities.
A final fun idea is maybe do takeaway/ eat in options where eat in uses a plate and takeaway a bag, with the option to wash plates.
