There are far more 'racial traits' available than are used in the current control files. As an old-time executable snooper I loaded the se4.exe into a viewer ages ago.

I've only used one so far, but it works fine.
Name := Natural Engineers
Description := Repairs are made at 150% of their normal rate.
Pic Num := 0
General Type := Advantage
Cost := 1000
Trait Type := Repair
Value 1 := 50
Value 2 := 0
Required Trait 1 := None
Required Trait 2 := None
Required Trait 3 := None
Restricted Trait 1 := None
Restricted Trait 2 := None
Restricted Trait 3 := None
This gives a 50 percent boost to repair rate as you would think. The abilities currently used in the default config are:
Supply Cost,
No Plagues,
No Spaceports,
Luck,
Vehicle Speed,
Galaxy Seen,
Planet Storage Space,
Planetary SY Rate,
Tech Area,
Population Emotionless,
Tech Area (racial techs, of course)
Other abilities listed in the executable, which may or may not all work, are the following:
Troops Bonus
Fighter Bonus
Ship Bonus
Mineral Production
Mineral Storage
Organics Production
Organics Storage
Radioactives Production
Radioactives Storage
Research Production
Intelligence Production
Trade
Ground Combat
Space Combat
Maintenance Cost
Ship Attack
Ship Defense
As you can see, many of them look like duplicates. But some experimentation that I don't have the patience for (Edit racialtraits.txt file, start new game, create race & experiment with new trait...) might turn up some others that are usable. Too bad there's not a "Ship SIZE" ability, huh? Having larger ships at all tech levels would be a cool advantage.
