It’s also worth noting that some of the Nik tools (eg, CEP & SEP) allow you to save the details of “recipes” (aka presets) as applied to your image … sorta like PL’s sidecar/.dop files.
I export & save these recipes/presets for each image that I modify using these Nik tools - knowing I can always export the original image from PL again - and re-apply the same set of modifications … as a starting point to continue where I left off.
