This is a great asset, my only suggestion would be to go through and set essentially absolutely everything to Hidden and untick the checkboxes for Position and Rotation for everything. I've seen the amount of atoms there is in it so it would be a lot of boring work, but it would make it a lot easier for people to use your asset in their own scenes.
Currently there are SO many atoms in the list it makes it rather difficult to work with, which is sadly why I have to pass on it. I could go through and do it all myself so I can use it, or I could just find another asset that is easier to manage. Other than that I love it!
By the way: It took 8 minutes and 35 seconds to change all controls to hidden and turn off possess/grab ... just in case you want to take the challenge. :D
