Hide 'All Tracks' Group
On our radio station, we have some explicit music in our library for shows late at night etc. We have group filters set up to make an "All Songs" group which doesn't show these tracks (so presenters can't accidentally play them), but they're still visible in the All Tracks group which some people accidentally click instead.
It'd be nice if we had the ability to hide this All Tracks group in order to prevent this from happening.
