- Population boosts.

- Ship shield and armor parts.
- Ship fuel and engine parts.
- Ship stealth parts.
Influence boosts are not yet sketched in any of my spreadsheets. I (or we) have to work on the possible influence upkeep equations (each gated through a policy, most probably), and then we can design and balance the other techs that boost influence output or reduce influence upkeep.
Detection and stealth needs a rework that ideally should be done before the new tiered themed tech tree is finished. But we could use current mechanics if that would be too much of a delay.
Planetary defense also needs a rework that, ideally, would need backend changes to allow for different weapons in a planet (instead of current single big shot per combat bout).
