I use Ableset with the latest version on Windows and Ableton 11.3.20
Unless I missed it, I didn’t see a way to expand all songs to show sections and also to collapse all songs. You can expand the current song, but I didn’t see an easy way to expand all songs at once.
I wanted to search for a certain section of a song and if you don’t know the name of the song where that section is located, I could not search unless it was expanded.
A short-cut to expand all songs and collapse all songs in the list mode would be great also.
