It would be very helpful to be able to place materials I am interested in downloading into "Saved Collections." Ideally, I could place the contenders into sub-folders to organize my desired content. This is a common service offered by other resource websites like Getty and Shutterstock.
It's wonderful that there are so many material choices, but remembering one from the other after looking at many is nigh impossible. Enabling users to create personal collections would dramatically improve workflow. It would make it easier for team members to present options and cull the choices.
