Hi paulpaul! I'm glad to hear you got things sorted. Unfolding choruses is certainly possible in the plugin and has been available for quite some time. The button that you are referring to was moved from under the chord sheet and placed above the chord sheet on the left hand side next to several other buttons. Above the chord sheet you should see 6 different buttons which from left to right are as follows: Zoom in (+), Zoom out (-), Chord Display (VI), Unfold Choruses (^), Chords to MIDI (C7), Preview As MIDI (>). The Unfold Choruses button is the fourth button from the left and looks like an upward facing triangle. Hope this helps!
