Functionality of the "Previous" button

[Jookman 5]

The intended use of the "previous" and "next" buttons are confusing. The history must ideally list all the notes that I have viewed in a session. However, the moment I expand a note the 'previous' button loses all its history. After that I can only toggle between this one note and its expanded view.

Quickest way to solve this would be to knock off expanded views of notes from the Previous button's history. The history must only retain a list of notes, not how they were viewed.
