BRX, I definitely understand the appeal of such a feature, but I think itsme has the right idea here. If I add a property to songs that determines if they are hidden or not, this is essentially like assigning them to a collection of hidden songs. In fact, your "Show/Hidden/Not Hidden" is basically equivalent to the include/exclude/unassigned options for the collections filter. One option would be to just place all your placeholders and other "hidden" songs in one collection, then you can select "Exclude" and filter on that collection. Or if you aren't using collection for anything else, you can assign all of those "hidden" songs to a collection and select unassigned for the collections filter to only show the other songs in your library.

The only difference I can see between what I've described above and adding a new hidden property would be if I made the filter selection persistent, as then you wouldn't need to set it every time. If that's all you really need though, I can add an option to save/reload the filter selections so that you would only have to set it once and then forgot about it until you need to edit a hidden song.

If this will not work for you or is in some way more cumbersome than a new property, we can discuss it further. I just don't want to add too much redundancy as it can get confusing/overwhelming for users (perhaps we are already there...).
