Interesting Stellar Abilities info...

[Krsqk]

None of the point generation or point generation-modifier abilities functioned on planets.

It is possible to get extra cargo in unmodded SEIV; build Cargo Storage Facilities on a planet. It's pretty pointless most of the time, though, as facility slots can usually be put to better use.

If you set the descriptions in StellarAbilities.txt to blank, the only way a player could detect the abilities is to test them. The resource conVersion button lights up when the planet is selected. The destroy planet dialog says the planet is protected against planet-destroying weapons. If you give the abilities a description, they appear under the Abilities tab when the planet is selected.
