Brought up by Mathias Jensen during Scenario Week 2021.2:
"Would be nice if the System category in VFX Graph was renamed to templates since that is what it contains. Would be nice if there were even more templates. Furthermore, there is not parity between all templates. For e.g. The simple mesh output is just an Output Mesh node."
We can rename the item from "System" to "Templates", Julien Fryer agreed to it in the comment section.
As for having more templates, we should check with TA what we want to have there (there was talk about some embedded template browser)
