What’s the name of the app you tried?

the coordinates aren’t there i think, but there are github projects out there that “detect” the panels and suggest split based on that. For most of the panels of most of the comics, that would be more than enough to do a clean split. I just can’t find a real relatively easily deployable service that incorporates it.

The main mess is genres. That is non existent in the folder structure (I do have it: artist > albums), and still very hard with Picard etc. But genres is very convenient for Autoplay, auto generate shuffle playlists
