[Gateway103]

You mean something like (as in Civ games),

Pass - Press say Ctrl-Space (Ctrl to prevent accidental space bar pressing...?) to skip this unit for this turn only, it's set to do whatever it is currently set to do. Just flag it (internally) so it won't be cycled through by the 'n' key this turn.

Hold - Equivalent to Defend, except require manual/divine intervention to un-hold it.

These would indeed be useful features. But to make it more complete, we also need a key to cycle through units with Hold order (Ctrl-h?), or at least units with Hold order should be highlighted somehow in the overview, least we quickly forget about their existence.

Just some random musings.
