How do you rename the default Home page, so you can use a different one?
You have to change the Home page before you can rename it. The home page cant be renamed.
Project Settings → Home Page… choose a new page to be the home page. Rename the old one.
@Malachiman, I’ve already made the new Home page. Are you saying, I have to make a new one?
Unless I mis-understood your question, I understood it to mean changing the page being used as the home page??
You use the Home Page setting to select the new page you made to be the home page.
