Ships display movement / target range?

[capnq]

But you can't get a distance measurement without actually plotting the movement.

You can, but it's really tedious.

select a object - planet, moon, ship, unit - and then put mouse over another spot. And in lower left hand side it should show distance.

Select the ship, put the mouse on the first warp point it will go through; add one to that range, select the other end of the warp point, put the mouse on the second warp point, add that range plus one, repeat until you reach the destination.

If there's more than one possible route, you have to trace them all to find the shortest one.
