Is there any chance of having the CAGs going automatically on "carrier protection" mission when there is nothing else to do, or when the carriers are under attack? It'd be a pain having to re-assign them every time, and it would really suck to lose your carriers because you forgot that.
If the fighters and attack planes are not seperated this could mean that if you want to have CAP, you cannot attack with the whole CV compartment. Plus the fact that you always would have to switch around between the modes manually (offensive/defensive).
