In kmail, Settings => Composer contains "Templates" and "Custom Templates" tabs, and Folder => Properties also has a "Templates" tab. It seems to me I remember someone here saying that he uses templates to autofill the To field of new emails; which of these three provides that capability? The Help Center manual for kmail mentions none of them, but has information for a "Phrases" tab in Settings => Composer, which I suppose was superceded by the templates?
