During games I like to gradually increase my star base area of influence outwards. I like to fill in the gaps of where my current ones are.
One problem I've noticed with placing star bases is that to find the optimal location for it you have to cycle between your previous star bases to find the areas that aren't covered.
The idea I would like to suggest is a button that will show all your current star bases' (of one type) areas of influence simultaneously, and a ghost image for the one you are about to place; like in SimCity for example. When you move the ghost image around and find the right spot you click and your constructor will move towards that area. When it reaches the spot, it starts building the star base as usual. This would help make better decisions and stream line it a bit. Thanks.
