Currently in Sumatra, if you do a “pinch” gesture on a touch screen, it changes the zoom. The Microsoft Reader app, which I used previously but which is being phased out soon, had a different feature: when you pinch inward, it shows an overview of all pages in a document, allowing you to quickly jump to a different page. Could you add an option in setting allowing users to change what the touch screen pinch gesture does, and implement this document overview as one of the options? I’m sure the zoom feature is very useful for most people, but for some this is more useful.
