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.
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.
