Question Features about Particle System

Hi! I currently have a Unity Standard project that is supposed to be immigrated to Tiny, but I met some troubles when using Particle System. I have already designed and edited a particle in standard version, using some modules like ColorOverLifetime, RandomBetweenTwoCurves, SubEmitters(vitally significant) and Trails(also important). However, I found that these modules are not yet supported in Tiny because I only got some wield output in a built project on any platform.
I wanna know when would Unity Team support these modules(may includes but not limited to)?
If I could hardly get the official supports about this issue in the near future, how can I extend the Particle System in Tiny for those modules that I mentioned?
Looking forward to hearing your answer, and Thanks a lots.

 

Thanks for your reply! I've already read all the docs posted, but actually there are some unsupported features that I want to use. The problem is that am I available to extend those not yet unsupported ones by myself?

Thanks
