Just a little hint for all people having issues to find the button for enabling the Developer Mode like I had: It is just listed below the list of themes. The guide is just starting with screenshots from the Templates functionality - possible a screenshot for the "Themes" page would be helpful. (in our case we had plenty of old themes still in the theme list & the button below was not visible without scrolling down)

ah yeah, I see... or don't :)
