Auto save while drafting documents; Shortcuts; Google Docs; Email as attachment;
Auto save while drafting documents in case of app crashing or ipad battery dying. I was working on a document and the app force closed on me and I lost all my changes.
Common Shortcuts would also be very handy such as to Save, copy, cut, paste, moving cursor from word to word, moving cursor to the beginning or end, etc.
Upload to and edit from (import) Google Docs.
