`label`	Optional	Tune label text
`onActivate`	Optional	Function to be called once tune activated by the user
`isActive`	Optional	True if tune should be marked as active
`isDisabled`	Optional	True if tune should be disabled
`closeOnActivate`	Optional	True if Block Tunes menu should close once the tune is activated. By default, the menu will stay visible after the tune activation
`toggle`	Optional	True if tune should act like a toggle (become highlighted on activation) Alternatively, can be set to toggle group name, which will make the tune behave like radio button. See example
