From c8ead63857d9bdd38d02ce031ea983a7a879295e Mon Sep 17 00:00:00 2001 From: Federico Mena Quintero Date: Wed, 17 Mar 2010 18:07:24 -0600 Subject: Start the mailer's folder sidebar with a reasonable width We do this by measuring a template string, which contains a sample name for an email account. This is what normally gets displayed in the folder tree, so such a sample string should give a reasonable width.
