This is a minimal clone of [thunderbird-conversations][1].  While contributing
to that project I found that I did not understand a lot of things. I used this
repo as a notepad whenever I found out how something works.

As a consequence, this project is **not meant to be used in production**. That
is not to say that it would not work. But I do not recommend it.

# Differences to thunderbird-conversations

-	I ignored most edge-cases to keep the code straight-forward.
-	No preview.
-	No quickreply.
-	The conversation view is not automatically updated when new messages come in.
-	The conversation view is only triggered when you open a message in a new tab.

# Things I learned while working on this

-	Many thunderbird APIs have next to no documentation. But reading the code is
	not that bad and it is easily searchable with [DXR][2]. Much of the
	thunderbird code itself is actually written in JavaScript.
-	The extensions relies heavily on [Gloda][5].
-	thunderbird-conversations was a [bootstrapped extension][3]. This has since
	been replaced by [web extensions][4]. Much of the functionality is not
	supported via the new APIs so thunderbird-conversations now makes extensive
	use of [WebExtension Experiments][6].
-	Plugging into enigmail is hard.
-	protz and Standard8 did an amazing job handling all those edge cases and
	making it work for humans.
