One of the main (for me at least) missing features in Material is a way to configure the browse-modes available for a player. There is no JSON API for this, and looking at the server.prefs file I see lots of _ts_disabled_myMusic** entries. Is there a way (via CLI calls, or perl code) to obtain the list of available browse modes, and which ones are enabled? For now at least, I'm not interested in creating new ones - just being able to list all of the existing ones (enabled or not), and to be able to control which ones are enabled for a player.
