In episode 431 of your podcast, you mentioned that hovering over the title bar of an open document will present you with a dropdown menu. This menu shows “rename’, “move to iCloud”, “move to” etc. I found that this menu (when opening a pdf) only worked in the native “preview” app and not in “adobe reader” or “PDFpen”. I believe that may point to this tip being for native apps only. Hope this proves to be a helpful tidbit.
