when playing Galciv 2, unless you wanted to micromanage all your spaceships you would quickly stumble upon an issue

all your miners would head toward the same area for mining (all accross the map if needs be)

your surveyors would tend to head toward the same area, same with scouts  resulting in lots of wasted time travelling all accross the map (of course problem is exaggerated by larger maps)

one suggestion, instead of completely automating a ship it could :

-improve/explore/survey nearby

-improve/explore/survey near home-star

-improve/explore/survey in a specific area (user draws a square to define it)

and also, action queues please !
