Power Grid view on big map

[Aeternus]

The Power Grid view on the big map is quite useful to see what's connected how, but it does not show problems well. For instance, if a power pole on a wide area grid is wrecked by biters, it simply shows as if there isn't any powerline there, even when the player built one. So a suggestion:
Show "Ghost" power lines by power poles that are planned, but not yet built, as "Red" connections on the power grid. That informs the player that the connection should be there, but the power pole isn't built or is destroyed.

Additionally, I've noticed that when a switch disconnects two parts of the power grid, it doesn't show as connected either. I recommend showing those kinds of connections (open switch) as yellow, to inform the player that a switch is open on that particular line.

These changes would make the Power Grid view on the big map a lot more useful in diagnosing power outages quickly.
