Just an idea: Have a graphics option to outline blocking triggers in game (so it's easier to see where you can and cannot go). Not an outline of each blocking trigger - just an outline of the connected blocking triggers.
Would be nice for finding pathing problems in-game. I've both lost an Intrepid that tried to go thru an asteroid field while being chased, and had a whole fleet go thru an asteroid field into enemy mining (was over anyways, but if that had happened before the battle was pretty much over...) Great idea yandon!
