Today we’ve launched a new feature that many people have asked for: a left-handed view of the fretboard visualization.
From now on, when you open the fretboard, you’ll see an icon at upper left that lets you switch between right-hand (default) and left-hand view. It’s the little hand icon.
Click that, and the fretboard will instantly flip to a left-handed view. Click it again to go back to right-handed view.
