I want to edit the existing page templates

How do I edit the page templates? I edited the "Services" page on the Pages list, saved it, created a new page, selected the Services Page template, and it gave me the version of the page from before I edited it.

I am surprised, and more than disappointed, that you can't simply "clone " a page once it is set up. This is causing me HOURS of additional work.

I think you guys released this too soon, if you did not put elementary editing features like that in here.

I like the theme, but it was clearly developed by developers and not users.
