Apologies if this has been suggested in the past.
The current icon mode function cycles between four modes: normal (enemy plane type, friendly ID), plane type (both enemy and friendly), friendly icon only (why is this useful?), and icons off.
I would prefer to see this split into two separate functions. One function to cycle between icons on, friendly icons, icons off. The second function would quickly toggle between CPID and plane type for friendly icons.
Personally I like to check on what planes the friendlies are flying, but want all icons on at all times. As it stands now, I have to hit the switch I have Alt-I mapped to a couple times to cycle back to normal mode after checking friendly plane types. Granted, it is a minor inconvenience, but on a few occasions I've inadvertenly landed in no icon mode, and that's not very good for one's health in this game.
