When I do training, a lot for people save their media on the Desktop or in Documents. I often spend several minutes teaching people how to add Desktop or Documents folders as favorites.
It's very confusing to people that the Media Browser does not show folders the way that macOS or Windows do. The file browsers in both OS-es show shortcuts to Downloads, Documents and Desktop.
Why can't these favorites be there by default?
You know you can do it! The Rush team got it right, so do what they did.
