The Editor puts every chord, barline, symbol, and text control in a single panel beside the chart. Open it from a song: click the pencil at the top right, press Cmd-E (Ctrl-E), choose File > Edit song, or right-click the song title. Save (Cmd-S, Ctrl-S) keeps you in the Editor and Done closes it.

 

The panel holds the space arrows, chord size, chord quality, alternate chord, invisible root, vertical space, repeat endings, time signature, text, and song info. Many of the buttons toggle, so click one again to remove what it inserted.
