Change the current starbase upgrade system from 'click on system/go down the page/click on 'Upgrade/go back up the page' until done to a list of systems you can select (CTRL-select or even just a checkbox) and hit 'go'. A way of prioritizing and automating construction would be nice - 'P1 Industry, P2 Science, P3 Amusement, P4 Money, P5 Don't build anything Just Alert the Player."
Seriously, there comes a point where I don't research anything that would provide a starbase update because I just can't face the micromanagement of building and routing constructors to 3-5 starbases per system.
Change the load transport/load colony ship screen so you know which kind of ship you are loading, and from where. I mean... HOW many months has this been going on now?
Change the planetary screen so that you can select something in the build list and move it up or down with arrow keys. Oh, and some way to expand the list so that you can see more than two things in the build list at once. Selecting and dragging DOESN"T WORK when the list doesn't scroll when you hit the top or bottom border.
Add some way to blow up all buildings on a planet at once, or all buildings of a certain type. Or even JUST ENABLE THE DELETE BUTTON instead of making me 'click on the building, go all the way across the page, click on destroy, go back across the page, click on ANOTHER building' and so on until I get carpal tunnel or quit playing.
And while we're add it change the stupid 'click on a building and go across the page and cancel upgrade and go back across the page and select the building and go back across the page and click on destroy' system of cancelling the upgrading of a building.
Oh, and add an easy way to change a factory to a power plant and a research building to one of the research assistance buildings without twenty mouse-clicks.
Change the AI search system so that it doesn't pile all my scouts or surveyors into one stack and leave the rest of the map unsearched. Or at least give me a warning when it does so that I can do something about it.
Add SOME way I can tell my unarmed ships "NO I really DON'T want you to survey pirate-infested sites" and a way I can tell my armed one "YES go get ALL of the ship graveyards!"
All of this has been in the game from launch. Stardock seems to be concentrating on adding new stuff rather than fixing the old mistakes so I have no hope they'll address any of this. I'm not going to insult the developers by saying they don't play their own game - they do, which may be the problem. I'm going to point out they could profit from having some newbies play it and make comments, or by taking some of these comments and actually fixing some of the UI issues.
Sorry if I sound angry, but I kind of am. Why do I need to tell you guys this? And keep telling you? And have you put out a DLC on angry squirrels and mercenaries instead of fixing clearly broken basic mechanics?
