Edit the Special:Header page and add the text [[NewPage|New Note]] and then click the "Save" button.
You now have at the top of every page a simple "New Page" link. Tap the link, and a new blank page it will open titled (ready for this?) "New Page". Enter whatever you want in the body, change the title to whatever the content is related to, click "Save", and voila! You now have a new page of content titled as you need it, and because you renamed the title, the next time you click the "New Page" link, you'll again be taken to a blank page.
The Special:Header page can be found bu entering "header" into the search field and tapping "Search for 'header'.
