We are missing some options to do massive detaching by elements, or by faces, or by group of faces that should be there by default.
So far only effective "Detach by element" script I know that works for huge amount of geometry is "Rayfire". But you need to pay 350$ for this basic function. I found some free ones, but they are super slow or simply fail when you deal with millions of faces/thousands of elements.
This will be terrible helpful for FX artist, and motion graphics.
