[SUGGESTION] Patrol command
A tiny suggestion
From time to time, I still play good old Empire Deluxe. That game is arguably the earliest computer game inspiration of the Civilization series, and it had a lovely Patrol command. You could use it to set patrol paths for your units, which they would follow until they encountered an enemy unit or you told them to go do something else.
I'd love to see a patrol command functionality in Elemental.
