Thank you for your comment Doof.
I do feel that I did things logically. However, all I am suggesting is that the a small feature is added to the software that protects users from making the same mistake. I must admit, I was a bit over dramatic about the problem when I first posted this topic, but I guess that's how I felt at the time.
To answer your question:I'm still not quite clear about why you maintain seperate libraries for Music and Photos and Videos. What benefit do you get from that?
Here are some of the main reasons why I like to do it this way:
1) I don't want all my pictures and videos available for viewing when I have friends over and I just want to play music in 'party mode'
I know that I can use: 'Access Control', but I am already using it for something else, and it doesn't seem to be able to create another 'access control'.
2) I have selected in options: 'Allow multiple instances (of MC) to run at one time'. I have two screens, and this allows me to have my music open in one and my photos/videos open in another.
This enables me to do more than I would if I used one library for all media types, some main examples are:
2.1) Switch between images and audio views without my pane filters resetting back to 'all'.
2.2) Change the music (or reduce volume) while watching a photo slide show (without having to stop the photo slide show)
2.3) Tag music and photos/videos at the same time.
2.4) Keep my music playing when watching videos (reducing the volume as much or as little as I like)
I have suggested a feature be added to that allows the user to open another window, which would allow you to use two screens with one library:
