You can delete files in recent uploads view in Office Lens, but it does not mean you can delete the file in OneDrive. Is your suggestion the ability to delete files in OneDrive from Office Lens??

Option to EMPTY Office Lens folder completely in stead of having to select each object you want to delete. Or specify the location of folder so I can access it with a proper file manager.
