"Trajectory tracer"

[Rash]

In some cases, it may be extremely useful to mark the trajectory of the projectile / grenade flight. Tom is an example of a grenade in the CS and demoman grenades from TF2. It would seem nothing serious, but in the case of demoman it would be much more convenient to throw grenades without spending time at trajectory calculating.
