Open Email Client

This is a simple email client on top of the notmuch command-line email indexing tool.

Before using this extension make sure you are familiar with the following terms:

1. notmuch: https://notmuchmail.org/
2. offlineimap (or another command-line email fetcher): http://www.offlineimap.org/
3. Maildir folder structure: https://en.wikipedia.org/wiki/Maildir

The extension has three sections:

1. "List" view: this view is capable of displaying entries in a search query
2. "Tree" view: this view is meant to list all the folders inside the root Maildir
3. "Search" view: this view is meant to offer custom search

The extension by itself is just a GUI for notmuch. You can add custom commands to improve the UI usability

Also, you can define a single periodic job which is used to fetch emails and display a toolbar badge text.
