Not plane or boat or tank but it would be a big wish come true if the mission screen had some changes.
I'd like to see an area where some text could be added for basic mission objectives and assignments, i.e. "NOE raid" or "De-ack and vulch" or "Fighter Sweep", etc etc.
It would be especially good to be able to put mission assignments in this text area, i.e. "P51's climb to 8K, drop ords on town, then CAP. P47's drop hangars and de-ack. Spit 8's protect the Goon at all costs", etc etc. 256 characters would be plenty.
If nothing else, it might cut some of the need for a monologue by the mission poster so we could get to the important stuff: in-mission sheep jokes. But that's me.
