Add notes to URLs.
Context Notes allows you to attach specific notes to URLs. You can leverage this plugin to add notes to
1. Specific Gmail email threads
2. Facebook friend profiles
3. Specific twitter or Instagram posts.
The possibilities are endless. If there is a url you can probably add a note to it.
When you open that particular URL again the app icon gets activated with a new red badge, indicating that a particular URL has notes attached to it.
*Currently all notes are stored using local storage and Chrome Sync.
