I'm aware that Calibre has a highlight feature, but is there a plugin or some way to make the notes accessible from the Calibre reader anywhere in the book? I'm reading a dense book with a lot of characters, and am having to keep a txt file of who's who. I'm wondering if I can just do this in Calibre instead.

If this isn't possible, then I'd like to request it as a feature. Even a basic Notes tab would be useful.
