I had started to do some work on a fix and polish update ages ago, but haven’t been able to carve out enough space to wrap it up. I know there were some rough edges starting to show following core changes, and I think there have been some longstanding challenges as far as compatibility with DiscoTOC.
Let me see if I can get some thoughts from the team on what the future of this component should look like. At the moment it’s still technically an unofficial, personally managed component.
