Ok, I can't find an official place so I thought I'd just start a thread.
My suggestions to the developers of GalCiv2:
1. On the planet screen, each of the icons represents an improvement. Though the graphics are pretty, it would be nice if they had a little mini-icon in the bottom left of the icon representing what TYPE of improvement it was. Like Research, or Economy, etc.
2. On the same note, it would be nice if the improvement icon had a mini-icon on the bottom right showing how MUCH X the improvement was generating (research points, money, etc.).
I think both of these things would make it easier to manage lots of worlds and also easier to learn the game.
3. Instead of alphabetical order, the improvments should be listed by TYPE. Otherwise everytime you upgrade a technology (Xeno Research -> Research Centers) it's position in the list changes. It makes hunting down what you want more difficult.
4. On the trade screen, if you could see the value (in research points) that a technology costs, it would make trading SO much easier. Again, if they could be grouped by type instead of alphabetical, we wouldn't have to uses a reference sheet to figure out what to trade.

I think that any improvements that make it easier to see cause->effect relationships of a user's actions make the game much easier to play and learn.
