In my opinion no asset should be marked as favourite unless I choose to do so.
The existing N3V policy marks all new downloaded assets as favourite by making them Rating 5 stars.
This is a bastardisation of the rating system that has outlived its usefulness (to ensure people could see all DLs). I'm tired of having to correct this.
There is also no need for N3V to mark builtins similarly, now that a colour sytem in routes and sessions menus differentiates builtins, downloads and own content.
