My feedback based on few hours played :
Is it plan to let the user customize the UI (Actually we can choose between big and small)
And depending the faction, will there be some design or shape difference ?
When we choose a planet or asteroid it coult be smarter to directly have the possibility to buid, Ships or Building, actually you have to additionnal click on the pannel, the first step has no added value, in an ergonomicaly speeking.
