CodeTV - Mark watched videos bookmarklet

readme.md

CodeTV video marker

This is a two piece bookmarklet to mark and highlight watched videos on CodeTV. It uses localStorage to keep track of the videos you have watched, so it has limited usefulness when viewing the videos from different computers.

Usage

1. After watching a video, use the CodeTV::mark_watched bookmarklet to add that video's uri into localStorage.
2. On the index page, use the CodeTV::highlight_watched bookmarklet to highlight all the videos that are in the localStorage bucket.
