I'd posted about this a while back (Back in 08') and revived the thread on it because it came up in a squad discussion the other night.
I'd like to see one that's tuned to a spicific VOX because if it's only available to squads, then squads with multiple wings wouldn't all have access to it.
Of course if you could add access to other squads that'd be a different beast all together.
One of the main problems with the mission planner, and reason I don't use it to plan out attacks...
You have to force what kind of planes/loadout people choose. Making a clipboard mission planner that isn't dependant on a time, or plane, but just has waypoints, ability to put notes on it for certain points etc. would be awesomely invaluable!
