The index page is always included in a remote because it is the homescreen/ main menu. For this reason the index page is mandatory and can not be deleted. But you can rename another remote page in “index”.
For this purpose you have to select the page you want to rename in “index” in the page list. Then click on the edit icon below list box. Now you can change the name to index. As a result the previous index page will be automatically renamed to “index (2)”.
