Future work:
	I want to set reasonable expectations for Ocarina 6 so that I don't
	have to spend a large amount of time coding before releasing something
	to the wild.  This section will be a list of features that I want, but
	should be deferred to a future release so basic support can be coded.

	- Fix track durations:
		Some tracks in my library are tagged with the wrong duration,
		so fix them as they are played.

	- Track tag editor:
		Make a pop-up window for editing the tags of a track.  Be sure
		to update the library information and the on-disk file.

	- Copy a song group to a different directory:
		This can be useful for keeping an external device (like an
		Android phone) updated with the music you want to listen to.
		Complications: I have an mp3 mirror of all my music, and I
		want the mp3s to be synced.  Perhaps track mirrors in Ocarina?

	- Mirror directory:
		I rip music to .flac, but keep an mp3 mirror directory to sync
		to other computers and phones.  An Ocarina tool to manage a
		COMPLETE library mirror might be a good idea so I no longer
		need to manage it externally.  This can still be done with a
		script, a cron job, and maybe a "mirror this track" option in
		the library?  Perhaps create a mirror group?

	- AirPlay / remote audio support

	- Replaygain support
		External script to calculate values?
		Calculate value after first playback?
		Store in library :: Track structure

	- "About" dialog
	- Ports:
		- OSX
		- Windows
		- Android
