Again:
To disable Images and Video, turn them off in Options > General > Advanced > Features.
This removes the media type from the tree, options, file types, etc.
Sorry for injecting some confusion. Your suggestion will nicely solve the needs of KStor since he only wants to manage audio files.
I have a different issue. I organize media by categories such as music, non-fiction, comedy, etc. all of which can be any combination of auto/image/video/document types.
No need to reply, I understand why audio/image/video views exist, just wish I could hide them, but I seem to be a weird outlier in the user community and I have a work-around.
