One of the real problems I'm finding with the game's interface is how it deals with units occupying the same space, which is to say, it handles it badly.
The problem:
If two units start in the same position, and you move one of them and give an order, the order is carried out by the unit still in the original position.
Example:
You launch two constructors from orbit. You move one constructor a few spaces away and give it an order to construct a starbase. The starbase will then be constructed by the constructor which has yet to move.
Needless to say, this is annoying, and counter-intuitive.
If at all possible, what I'd like to see added is a "create fleet" button, which would take me to the dialog showing all the ships in the space the selected ship is in (that is, the one that shows by default in such a situation). Otherwise, I would like the unit selected to show up like it would if it was the only unit in the space.
