Here I propose an option (with a patch) to capitalize the first letter (ucfirst) of default titles : filenames and urls can be lowercase but title are displayed with a capital first character (filename = "foo.mdwn", pagetitle = "Foo"). Note that [[!meta title]] are unaffected (no automatic capitalization). Comments please --JeanPrivat
