Custom Templates for KMail
Thanks to Dmitry, the KMail in the $SVN/branches/work/kdepim-3.5.5+ branch now can do Custom Templates. Look in the KMail configuration, under the Composer page where you'll see a "Custom Templates" tab.
I'm not sure if we still need the Templates folder feature... hmm...
