Seems like a very obvious (and missing) feature, but maybe I'm missing something. If we have a generic "page" template how could an editor (as in someone not confident with using settings) just create a new single page?
E.g they may have singles for about, history, faq's etc but then want to add a new "page" for a one-off thing. Right now the developer has to create a new single in settings for them which is really clunky.
