Just a couple of ideas. The ship list on the main screen. Don't get me wrong I liked having it since you introduced it a long time ago. The problem comes in when I change a ship like changing a constructor into a starbase; when, that happens the list starts over. It would be nice if instead the list started with the next ship that was in the list.
Introducing uncolonized planets on the planet list on the main screen was a good idea, but introducing opponents colony's that you have discovered lists would also be a good idea that way I don't spend a long time looking for a colony; sometimes, not finding it to send a freighter to, to avoid war. This needs to be carried a little further grouping the planets by civilization, and showing the civilization capital first. The civilizations should be alphabetetise first; then the colonies; other than the capital needs to be alphabetise.
It would be nice to add an option to double click to select a tech, and return to the main screen when selecting a tech through the tech tree to research.
It would be nice on the main colony screen if in the build list you could double click to delete a build item. This would also be nice in the shipyard.
Can we put the ship builder back on the main menu.

In multiplayer the taxation setting it skips inconsistently when you try to use the arrows to use the tax slider.
