When you are awarded ships like a colonizer from exploring space wreckage and you have no use anymore for the colonizer (all usage planets are already colonized) - what happens to the colonist onboard if you upgrade to some other type of support ship - trade ship - construction ship etc. Ideally the colonists would be evacuated off to the closest planet. Currently there appears also to be no way to see how many people are onboard a colonizer. Why is the mass of the non-prototype survey analyzer so high - seems perhaps twice as heavy as it should be.
When building troop ships - what is the requirement for being able to load troops onto troop carrier - it appears to only be possible to load from the primary owner of the shipyard.
Similarly generating colonizers - colonists only seen to be able to come from the primary owner of the shipyard. Are both of these design features - is there a distance limitation - this something that can be modified in the future so you don't have to have as many shipyards to make mass troop transports.
I notice having traded for Planetary Invasions without obtaining War Machine under the Warfare Tech research tab that I can implement invasions without the previous technology. I don't see issue with trading for techs out of sequence - currently difficult to tell when doing trades it be nice if you were able to browse the tech tree while making up trades - but it would seem to me that you should have researched or traded for the previous tech to be able to utilize the later tech.
Seems strange to me that a Cargo ship with three construction modules all get consumed to make a starbase. I like to see the others remain on the construction ship and/or be able to upgrade the shipyard with additional sensors, weapons, or defenses just like you can for a starbase. Similarly it be nice to have the obtain not to use all the available construction modules when upgrading a starbase. Sometimes you just one upgrade per star base but it cheaper and/or faster to make a multiple construction module construction ship.
Another UI update suggestion - when you get a colonizing event and get to the selection screen it would be nice to see stats on the planet that it is effecting - also would also be nice to see the impact on your current ideology as it would be impacted by your selection - see what points you have already earned - see the benefits of each ideology choice (ie be able to browse the ideology tree)
From the Governing Screen would be nice to be able to go to explore each planet - able to go back and forth see what being researched - built on each planet with some kind of popup screen for each planet if you hover over each named to see what is currently being build and what is already there.
