This functionality is already built on the back-end, but not implemented in the UI just yet.
We need to finalize how it'll look in the designs
Will probably be accessed from the Page metadata section
each page will have version history and a filmstrip slider to scrub through it
scrubbing through the filmstrip will have Haptics like in Apple Photos
kinda like GitHub for Thought
