I think it would be extremely helpful if we could have folder for pages.
Here is the case I am running across now: My team uses one file to source all the final designs. We have different release versions but with multiple features and pieces of the product. An added problem is multiple dev teams are working on this at the same time.
What would be good is to create a folder for one version and all the features included within it on separate pages.
This can make sections collapsable and help focus people on what they are looking for
