I suggested this way back when GalCiv2 was fairly new. I believe I had some positive feedback as well. It's surprising that a lot more people don't appear to've had the same idea and campaigned for it. What was my suggestion? It's simple, really, and excellent.
The mini map in the lower right hand corner shows you where the stars are located, and the planets, after you have necessary tech. The main map should show the same info. We all check the mini map to determine where to explore. We all have to compare it to the main map to get an idea of which quadrant has a good concentration of stars or planets, and where exactly in that quadrant we should set as a destination.
There's no logical reason that we should have to do the extra work. If we squint and scrutinize hard enough, we'll know right where to go to give us the maximum chance of spotting planets before moving on. Why not save all that effort and show stars in the FOW? All the races would start with the tech to identify star types and locations, so stars could appear just as they are. Planets could be blank circles in the FOW, and only appear when the requisite tech is researched.
Thoughts? Damned if I can see any drawbacks.
