An R3 Feture that should be included in R4

Why was a mandlebot scene not included in R4 but was In R3.
I think that in "scene and fade" "scene categories" could be included
So that "tunnel related scenes" could be toggled or "fades" could be colectivly turned on and off, insted of going through each one indidually.
That would allow less popular or simpler scenes to be included but off as default.
Could be a catogry called "oldschool scenes" that was off as defult for example.
Im a fractal artist and I think that cirtain jula\nova fractal sets with the correct colouring method look great. I may be able to help.
