I'm pretty sure someone will make something similar (i.e a list/meeting place for pilots, gunners, RIO's etc.) as soon as multicrew becomes a reality in DCS.
Yea, been longing for multicrew with a "study sim" and modern helis/jets since then - espescially a AH-64 sim! It is possible in IL2 as well as ArmA 3 (and probabaly a few more) but workload for gunner is a bit low.
