When in the song dashboard and trying to get back to the Home screen, it’s far too easy to hit the Save icon instead of the Home icon thus overwriting your song with changes you might not want.
I suggest adding a “Confirm Song Overwrite” option in the Behaviour settings. If enabled this would require a second press to confirm the overwriting of a song, useful in the case it was pressed by accident.
This option could of course be disabled for those who find it inconvenient.
