Similar to the earlier suggestion of the building count,
is it possible to have the ability to have a servants count.

It definitely comes in handy in several ways.
1) When a new servant is introduced due to a new Technology being introduced.
2) As an example
when trying to increase Tool Production
might be resolved because you have a low servant count of either "Metallicus Stagni", "Aeris Metallicus" OR "Lignum Servus" compared to the other needed servers
or rather than needing more mines, smelters, tool shops OR population
