For new players it would be potentially helpful to know when a new stockpile is needed and for players with big towns they may wish to have to options to get notifications of where stockpiles fill up so they can either use that .aerial up or create a new area.
How i see it going:
name stockpiles or descriptions: weaver/mason stockpile or food/stone stockpile or upper level/outside stockpile
When: when a stockpile is full or almost full
Action: player gets a notification on i button saying “Mason stockpile full”
Reason: to stop stockpiles being full and material littering the town
Toggleable: yes so messy people can turn it off
