I'm having trouble now - some of my Special: pages 'disappeared' from TrunkNotes when I type "Special:" as a prefix to find the pages. The pages still show up on Dropbox (on their website).
I can only get to Special:Header now by finding a previous link to it from a page (e.g., the manual). I can then 'edit' the page (which is blank on the device -- although the Dropbox version shows the original content), but when I attempt to save new content it complains that "'Special:Header' is not a valid page name: A page cannot have the prefix Docs:, Special:, New: or File:'"
I only began seeing this around the time of the recent IOS upgrade. Not precisely sure exactly what may have triggered it. (For a brief period, I was also using a MAC and synchronizing Dropbox between TrunkNotes on iPad, MAC, and PC. Not sure this is relevant, but prior to that was only ever using Dropbox sync between TrunkNotes on iPad and my PC.)
So for now, I am forced to live with blank header and footer which I can't customize
