This is simply a request to the sins developers to see if they could add any or all of the following constraint values (based on current statCountTypes) for use in modding in the next patch.

CapitalShipBattlship
CapitalShipCarrier
CapitalShipUtility0
CapitalShipUtility1
CapitalShipUtility2
FighterCombat
FighterBomber
FighterMineLayer
FrigateSpawnedByAbility
FrigateAntiFighter
FrigateCarrier
FrigateColony
FrigateHeavy
FrigateLight
FrigateLongRange
FrigateMineLayer
FrigateConstructor
FrigateRefineryShip
FrigateScout
FrigateSiege
FrigateTradeShip
FrigateUtility0
FrigateUtility1

I was attempting to create some synergistic abilities based on ship type and was dissapointed to see this would not be possible with the current set of constraint values.
