Did what you asked, seems to be related to some SC files and not others.
luxinate_temporary.part appears everytime however some target files then convert, others simply never appear. luxinate_temporary.part dissapears in either case.
Many thanks! It's such a great workflow and i appreciate your efforts.
* except in some cases, as i just found out, luxinate_temporary.part dosent appear at all. confusing! file types? tags within file types?
