I have added three new default orders:
Load Colonists at Capital (max 4 jumps)
Load Colonists at 20m+ pop (max 4 jumps)
Unload Colonists < 15m within 4 jumps
This is really for future use by NPRs when I add minor races but it can also be used by players. If you set the primary default order to either of the Load Colonists orders and the secondary default order to Unload Colonists, a colony fleet will work on automatic. When it runs out of orders, if there are no colonists on board it will look for an appropriate place to load colonists and if there are colonists on board it will look for a suitable place to unload them. Suitable unload destinations are any colony that is either ideal or has more infrastructure than it needs. Distance in jumps is the first filter with smaller colonies being the main factor for those of equal distance. At some point I will add the ability to found new colonies on uninhabited ideal world as part of the Unload option.
Both Load Orders will automatically add Freighter Maintenance Check (if a CFF exists) and Refuel Orders at the pickup point as well.
It will probably still be better for players to control fleets directly but if you have a small race you are not as bothered about, put the colony ships on automatic and leave them to it.
