Subject: [PATCH 2/7] view: optional flat view for recent messages
Date: Wed, 2 Sep 2015 06:59:34 +0000 [thread overview]
Message-ID: <1441177179-16628-3-git-send-email-e@80x24.org> (raw)
In-Reply-To: <1441177179-16628-1-git-send-email-e@80x24.org>
For still-active threads, it will likely be easier to follow
them chronologically, especially if we have links to parent
messages.
