Feature Request: Manual Bookmarks Within a Novel

I'd like to suggest adding manual bookmarks within a novel.

I don't mean the current reading progress or Continue Reading feature, as that already remembers where I left off. What I'm suggesting is a separate bookmarking system that lets users save specific chapters or even paragraphs they want to revisit later.

Instead of creating a completely separate bookmarks page, I think it would be much more user-friendly to integrate bookmarks into the existing Contents/Index panel, similar to the concept shown in the attached screenshot.

Some ideas:

1) Allow users to bookmark an entire chapter or even a specific paragraph.

2)Support multiple bookmarks within the same novel.

3)Add a Bookmarks tab alongside the Chapters tab in the Contents/Index panel, so users can quickly switch between the chapter list and their saved bookmarks.

Each bookmark could display the chapter title (or chapter number), reading progress (if applicable), and the date it was created.

This would make it easy to:

-Revisit favorite scenes or arcs.

-Save emotional or memorable moments.

-Keep track of important plot points or references.

-Jump back to saved locations without remembering chapter numbers.

I think integrating it into the existing Contents panel would keep everything organized and easily accessible without adding extra menus.
