I totally agree with everything here.
1. Especially with the auto end turn, I found it hard to figure out if it was still in one turn, or moving in the next. Having a movement bar that was visible and intuitive would really help, especially on the icon in the top left, so I could see who has movement points at a glance.
2. Maybe not blink, but identify them somehow. It should blink when you zoom out to the strategic view. Double clicking things should snap you to their location.
3. Yup!
4. Yup again. I was looking for this forever, assuming such a feature would be so obvious in a 4x game I just must not be seeing it.
