First off, I'd like to know what exactly I might have done to you good folks to deserve having the Dark Yor camped right next to my homeworld on the very first map I start in beta 5! 
On a more serious note, I was just now wishing for the ability to set arbitrary navigational waypoints for my explorers to help them avoid stuff and such. Maybe ctrl-right-clicking to set a sequence of points that the ship will attempt to navigate to?
Now back to see if I can save Earth from the Dark Yor in turn 15...
