remember the last page of each note.
That can solve also the last page request, as the user was probably at the last page, and give extra capabilities. It is the most intuitive solution as it l like each note is open in its own application, and it remember the last state as expected.
We just released an update on Google Play today (v0.7.0) where notes now open to the last page viewed by default (this can be disabled in the settings). Also, you can jump to any page in the note by tapping the current page number.
