Also here to +1 the ability to select which non-media files are included when using the file organizer.
Before the 3.6 update, the organizer would always include booklet.pdf files regardless if the non-media files option was selected (I actually prefer this).
However after the update, the only way to include booklet.pdf files is to include everything, which I don't really want.
Being able to select what file types (or even exact file names) would be a very useful enhancement for the file organizer to handle non-media files.
