Preface by saying very much enjoying the game so far! Also that if this feature is already implemented or planned and I have missed it, apologies!
I was wondering if a pathing preview could be added to ship movement. This is a feature in a number of other strategy games where you select your unit, right click and hold on the map and you see a preview of the path it will take to reach the target, as well as the markers you get at the end of each movement segment saying how long it will take to reach the end of each segment like on the current pathing after the ship starts moving. Then you can move the cursor and see the path dynamically update to better judge where you want the ship to end up.
Hope that all made sense!
