I'm looking for a JavaScript component that would support discussions for my read-only HTML documents, a-la what modern Google Documents do.
User selects a random portion of web-page, presses a hotkey / button on the page, and a comment floating pane appears. Portions of web-page that have comments are highlighted in some way unless user disabled that somewhere.
Should support or me allow to easily implement:
- Several users (I provide information on the current user).
- Sane API for server-side, so I can implement it and not take whatever PHP stuff is bundled (even better if it would be abstracted away on JS code level).
- "Resolved" function (actually, it would do if I'll be able to put any custom button)
- Change / delete functions
- Comment stream pane
