While I know there are some other issues with the sector map, I would like to point out it would be great if the popup information telling one about the number of systems in a sector, ongoing enemy invasions, the number of fleets in the sector and the amount of shipyard construction points would be displayed permanently. I know it does not look as good then, but it would help massively in staying up to date with everything going on. I lost track of a few invasions later in the campaign, so that's one thing for example. xD
