Breaking this out from the main extras thread:
Thanks for adding extras…fantastic long awaited feature. Unfortunately the feature has sort of broken my library.
As of 8.4.1, I suddenly have 300+ new “movies” in my library. Turns out they’re all extras.
A lot of us have likely been organizing extras for years in anticipation of integration into Infuse. So I’ve been a little caught off guard by the limited folder naming styles.
Many are just in “Extras” and “Featurettes” folders but others are organized into subfolders that mimic the menus on the Blu-Rays & DVDs they came from.
Example:
With 8.4.1, the 7 featurettes that aren’t in subfolders show up under the main 4K DV movie:
But everything in a non-recognized extras folder naming style is either a different version of Minority Report or its own movie:
I promise I don’t have 16 versions of Minority Report 
! The other 15 “versions” of are just 1-3 minute extras. Infuse added the rest of the extras as their own movie.
With the hundreds of extras added as “movies”, my library now looks like this:
Can we have any subfolder name within an “Extras” or “Featurettes” folder acts as a custom “naming style”? This way videos within a subfolder called “Storyboards” or “From Story to Screen” don’t get added as random “movies” based on the title of the extra?
Or at least an Extras on/off settings toggle in the meantime?
I’m a bit lost as to what to do in the meantime as I suddenly have 300+ extras showing up as “movies” mixed into my library. And I’d rather not think of the hours it will take to go through over 1500 movie folders (+ dozens of TV series folders) to find which ones have extras/featurettes with unrecognized subfolder naming styles 
Thanks!
