I created a new library to work with audio files that are not part of my main music collection. This worked well, but a couple of things were unexpected.
The main library had some filters that I created for subsets of the whole library, with specific search criteria. These appeared as folder items under Music at the top of the navigation panel. When I created the new library, those same filters were there, even though they'd be meaningless to the new file set. The playlists from the main library were not in the new library, nor were (I don't think) the paths in the Scan Folders For New Files dialog, as I wouldn't expect them to be in a new library. But the filters were retained. I deleted them, because, why not?
Later when I reopened the main library, the filters were gone there too. Which I also didn't expect, but maybe I should have...? It's not clear how it works, or why it would work as it apparently does.
I also found that changes I had made to the displayed fields of the new library's Music node that were specific to its purpose were propagated to the main library. I really didn't expect that one!
I would have thought libraries would be separate from each other, or could be made more or less that way. But I'm not finding options related to this, or enlightenment in the wiki.
What is it I'm missing?
