Whenever I remove a file from the library it's gone for the current session (until I close MB) but once I restart MB the file pops back up again. Notice I only want to remove it from the library, but still keep it on my harddisk. As an example, I have an album but I don't like two songs and I don't want them to show up in my library, the current system just removes these items from the current session.
Would it be possible to have a checkbox or an exclude list in the preferences? So in a way you could set your library at D:\Music and inside Music exclude folders A and C, but manage B and D for example.
