I seem to have all the dumb questions... so I apologized in advance 
In GCII (when the shipyard is also your planets), you don't have to have a ship building queue if you don't want to... the game will allow you to end the turn even if you are not building anything anywhere. With GCIII, I can't seem to find a way to leave the shipyard idle (or the colony or my current fleet). Before a turn, I *HAVE* to build something or else it don't let me finish the turn. Of course I can 'shutdown' the shipyard for the time being, which is what I have to do now, but I thought maybe there is another way to leave the shipyard idle until I *NEED* to build something.
Also, is there a way to leave starhips in the map idle as well? Right now I have to put them in 'guard' mode or I have to 'pass' each one of the ships I don't want to move. It gets annoying as my fleet grew. GCII I believe don't care much if your ship stay idle in one position....
