The present behavior does encourage you to zoom in and appreciate the artwork, and I do need good excuses to do that.  I really like ships arriving at a rally point near a planet with starbases, f'rinstance.   However, I envision bigger maps needing even more strategic viewing.   I find myself wishing I could zoom out one more level.  I am not sure how it would look visually, and I wouldn't want to break the present transitions between levels.  Maybe I could get the minimap type display swapped into the main map window.  It could cover wide swaths of galaxy.  That could be useful.  Spiral galaxies could look real cool.
I like the individual ship highlight suggestions made.  I have faith that the devs will find something clean and useful out of all that.
