If "special energy" would be renamed to "auxiliary power", I'd be happy.

Sounds better to me.
But I don't think we need that special-shield-energy-feature. In my opinion FO is already complex / complicated enough - to better say: Everything's fine the way it is regarding the options you have to command your fleets.
And: There are some special-abilities coming up in V3 which are equal in their effect to your request, ewm.
But what about more formations? I'd like to see that... and I do know that this question is off-topic
