Is there a way to add a tracer?

[MrPrezident]

I would like to add a tracer to my simulations (Similar to Algodoo tracer). Is there a way to do that? It seems like the emitter feature is close.

This reminds of something achieved with SketchyPhysics: https://3dwarehouse.sketchup.com/model/a5987d5dc38e7e53d595b43ed271a30e/Streamer-FX

There are a few ways to achieve this. One way is to compose out of geometry. Another way is to have a trailing set of particles
