This is actually not a bad idea. As a commander I have had plenty of

moments where some bright chap points out "hey, we should galv meesh". GUESS WHAT I'VE BEEN TRYING TO GET YOU TO DO FOR THE PAST TEN MINUTES, EINSTEIN. Bold chat is clearly not enough. Bold, all-caps, angry spam chat is also not enough. The chat scrolls too much.
This is well recognized, and in the past we've had crazy proposals like being able to "flag" sectors on the minimap or have some sort of drop-down panel where commanders can twiddle commands for individuals and for wings. These have all been too complicated to manage. But a simple, single-line "standing orders" for the whole team could fill this communication gap nicely.
Extra points for being able to put standing orders on a timer: e.g. "#countdown 60 Bomb palain from thrale when bombers up.", "#countdown 5 Uncamp meesh".
