With the new expansion, I've gotten back into GalCiv2 after about an year and have some comments about the user interface:
1) Supposedly there's an option to keep functional components when you're upgrading a ship but for the life of me, I cannot find it. When I'm designing a ship upgrade I want all the functional components to stay in place and the available hull space to be recalculated based on my current miniaturization tech level. Even better would be adding an option which allows me to optionally upgrade components with newer versions (e.g., replace Laser II with Laser V).
2) When a ship is guarding a starbase you can't see how many components are available to be upgraded. Maybe place this number above the starbase?
3) Similarily, right now I have no idea which asteroid fields can be mined further besides having to click on each one. A number shown above the field would be very helpful. BTW, is there any reason why a miner has to move off/on, off/on, etc. to improve an asteroid field through to Mining III?
4) This has bugged me since GalCiv I. Please, please, please add a button to the Colony Management screen that pops up a screen showing where the planet is on a galaxy mini-map. Using the current mini-map (showing the info the player has chosen) is fine; a bigger version would be better.
