We should be able to remove access to a subfolder without it affecting access to the parent folder. I understand cascading permissions from parent folder > subfolder, but it definitely should not be the other way around. Currently, we have a parent folder with tons of different subfolders underneath and when we create a new private subfolder, rather than having to un-share the parent folder with someone and re-share all folders except the private one, we should just be able to un-share the private subfolder without taking away access to the entire parent folder. This is a huge time-eating hurdle for us, so if it were fixed it would be a big improvement!
