Or an NPC..
Basically it would be very nice to see somewhere a list of all plots requiring building work, and which ones pay. Filterable of course!
For example
I'm a lvl 27 mason. Happy to work sandstone or slate.. I would like to be paid, but if not paid, would like to know where I can apply my skills - I'd far rather level up on building than making tools!
Tick box : T1, T2, Stone.
Get a list (sortable) of structures requiring those resources.
Should have: location, building unit type needed, value per unit paid.
When someone is working on their plot (as in redesigning it), a flag is set so that it won't appear on this listing until the design changes have been finished - ie plot design window closed. Maybe updated once per hour? or live data..
