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 a 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.
