Most troops have two troop types and I often want to search for troops with two specific types (eg. human knight) but there is only 1 troop type option in the search. Having two would probably look messy and one of them would often be unused however.
So I thought what about adding Troop Type to the search Order?
Therefor if you search for a troop type, and set the order to troop type, All of the 2nd troop types would be grouped together.
