Seriously cannot believe that Presentation Mode is no longer available on iOS. I've worked in software development for years, and am a long term premium users of Evernote. It makes absolutely zero sense to implement a very useful feature, and then remove it on one of your main platforms.
Personally I use presentation mode extensively when I'm speaking (as speaker notes for me). It has easy to read typography, the ability to use note links for navigation, and I can setup the individual pages to show exactly what I use per page.
However I can't use my iPad when I'm presentation! Crazy and very frustrating. Totally makes me want to find a different note taking app.
