We've had occasion to work with a division that decides to collapse a bunch of nested spaces into a single space. With the current Admin Console structure, this is time consuming. And due to the manual nature of selecting one at a time, it is prone to error when you are repeating the same steps many times in a row.
I suggest offering an option to collapse all/some nested spaces in a single step. This could be accomplished with checkboxes. It would make it much quicker in terms of the number of steps. It would also make it less prone to error.
