On multi-touch platforms, WeWrite will utilize various gestures.
Pinch gesture to manipulate text size and spacing.
When in the filmstrip view for viewing the version history, that same pinch gesture will be used to zoom out on the block of text so you can swipe through and see a timelapse of the page changing over time.
Swiping down on the page title will open up the backlinks and forelinks diagram view of related pages.
Gestures under consideration
What will left-right swipes do? Previous / next? Where will such a collection list come from? Next could bring users to "Related pages" which could encourage exploration and discovery?
