Bump!
Seriously, if money is the problem, make good UI a DLC, I will definitely buy it.
Yes, this info is shown on a tooltp, appearing after a short delay, but as player needs this info constantly, milliseconds add and considerably increase turn time. After brilliant work on AI turn times in 1.9, how about decreasing player turn times?
Other stat hidden in fleet UI, compared to single ship UI, is range. But it does not create a problem since range is perfectly visible on the map, and when player occasionally needs exact value he/she can spend a second to look at the tooltip.
Movement lines on the other had are displayed buggy on the map (since beta, Karl!), not remaining moves are shown, but rather max moves. Hence the problem becomes even more important.
