I understand exactly what you are saying. However, IL-2 still has some of what you are looking for. As I mentioned earlier, you can use custom icons so that you really couldn't see them at all. As far as this part you mentioned...."different effect in searching and padlocking in sky various aircrafts: "E" for enemy, "F" for friend and much more."....IL-2 already has the following Padlock commands:

Padlock Enemy
Padlock Friendly
Padlock Enemy Ground
Padlock Friendly Ground
Padlock Next
Padlock Previous

All of the above are INTERNAL (in-cockpit) commands. They seem to do exactly as you have described above.

I do understand that you would like your virtual pilot's viewing system to be more human-like. I agree. That would be great. (Be aware that there is a large percentage of IL-2 players who are totally against Padlock and disable this feature altogether from their server(s).)

Personally, I use Padlock. Could it be improved? Just about anything in IL-2 could be improved. However, I have been playing flight sims for many years and in my opinion, the Padlock implementation in IL-2 is the best I have ever seen. (Yes, I also played Red Baron 3D.)
