I created a new page and found that I needed to change the page name and title. There is no feature to rename a page. Since I only had a couple of blocks on the page, I edited sys_page_compose_pages to change the name of the page and title and then edited the sys_page_compose to put the blocks back on the correct page.
How difficult would it be to be able to change the page name and/or title from the Page Builder and have it to update sys_page_compose to put the blocks back on the page? Of course the user would have to go to Navigation builder to update the link but that is easy peasy.
