Changing the name of a Pages, Keynote, or Numbers Document
Everyday I learn something new about iOS 8+, I love finding the new features that accompany Apple's stock apps and their productivity tools.
For instance, in the previous versions of these three programs, you had to start a document and then close the document, tap on the name, and then change the name of the file so that they weren't all Blank#. Now, while the document is open, just tap the name and you can change it right then and there. No more having to add the extra steps. Thank you Apple!
