I noticed that when I try to save a game the dialog for overwriting an existing save is not visible until I back out of save and the menu all the way back to the game. Then the dialog asking if I want to overwrite an existing save game is there.
When I first colonize a planet I would like to have an option of going to that planet to set my build queue. Maybe another button on the dialog that allows me to set it's name.
When I am building facilities on a planet I find that any yellow areas (soil enhancement only) often get selected before the green ones. Of course I can just select a green tile and then select what to build but then the yellow tile is again selected next, so I usually just build Soil Enhancement and move it to the bottom of the queue when I am done. However, when moving items in the queue I find that, if the list is long, it pops me back to the top of the list instead of showing me the position of the item I am currently moving.
When a planet builds a facility I get a drop-down icon showing it, which is great. Right clicking removes the icon now which is also great. However I often get a second icon for the same build on the next turn which is not as great.
I have not been able to get the game to run for more than about 30 turns so far. It always crashes to desktop then or earlier.
