It seems virtually impossible to create a Folder structure to organise Product Notes. Maybe an add folder button? When I try to drag one Product note so that its visible as a sub note to a higher level topic it does not seem to work - only a flat list seems possible.
Thanks for submitting this idea! It is possible to organize your notes as sub-notes within other notes. We have asked our Customer Success team to reach out to you to assist. You should hear from the shortly.
