I have put together a simple chapter viewer and editor plugin. The plugin is now in the plugin catalogue. As always, here is the source: https://github.com/faush01/ChapterApi/tree/main/ChapterApi It is very simple and allows you to view chapters for an item (Movie, Season or Episode), remove chapters and add them. It supports all the different chapter marker types. It also has a season Intro summary page, select a season to see if it has intros detected for each episode.
