Feature description:
It would be great if we have next and previous chapter controls that can be added to the Now Playing page. Bonus if these are available as options for cover art actions.
Problem solved:
For music, I use chapters for long multi-part tracks, e.g. Mozart Great Mass, rather than splitting them up into several tracks for each part. Sometimes I want to skip forward or back to the next part. Organizing it as a single track with chapters allow shuffling playlists without messing up the internal order.
This functionality is also useful for podcasts (that have chapters) and audiobooks.
Brought benefits:
Quick chapter navigation back and forth, compared to selecting chapters from the dropdown list.
Other application solutions:
More commonly supported in audiobook and podcast players, than pure music players.
