I agree with the need for footnotes/endnotes/references etc and even an index option for a writing programme. I had not realised that these functions were absent on the iPad until I started writing.
I wanted to use this app to write up our family histories but without these options this app is not suitable. That is really disappointing.
I suppose I may use it as a text editor and wait until Scrivener brings out the iPad app but I have things like Pages and PlainText etc already! Frustrating - I had started to like this app!
