Slip indicator option (or maybe mod?)

[Pilsner]

Would it be possible to have a setting to stick a yaw string on the canopy or nose to see if we are slipping while turning without having to look down on the turn coordinator and possibly losing visual contact with the plane we are in dogfight with?

Lots of people use this in real life even on an f-14 and U-2 (see pictures)

It would be really helpful with alot of aircrafts in the game that don't have a fly by wire control system.
