I, and I'm sure many others, spend a good deal of time pinning and repinning moving units. So, what I propose is to modify pins so they can be targeted like air attacks. If a pin is set on a ground or naval unit, the pin will move with that unit, along with any comments made. Pins could also be set to a sector to mark stationary units/bases, or just to say a message.
Yes? No? Doable?
