I would like to see an option where I can have the scanner disregard certain subfolders within my media. My particular use case - I have a Photos folder, and within that, I have my Lightroom library. The Lightroom folder includes preview images that Lightroom creates, and Plex is now indexing those as well.
If there is not already one, could you add a “do not include” section of the Search Folders page? If it had to be a robots.txt-style separate file, that would work too.
