Where are Avisynth Plugins

[PizzaTime]

Hybrid does not automatically magically add stuff to the GUI.
Assuming you know your way around Avisynth, which I assume, since I don't really see a reason to use it myself.

You can either:
a. use a custom section and load and use your filter there
b. write an xml which tells Hybrid how to integrade the filter (https://forum.selur.net/thread-3231.html)
Where you place the dll of a filter doesn't really concern Hybrid since filters are loaded explicitly. (auto loading is disabled)

No, there is no chroma shift filter integrated into Hybrid for Avisynth.

Gotcha. Thank you, Selur!
