Implement flick-scrolling

[Rohaq]

Right now, scrolling is purely click and drag - you lift your finger, and the scrolling stops where it is - which makes it a huge pain to scroll through anything in comparison to say, mobile web browsers, where you can flick up or down, and the page continues the scrolling inertia until it slows to a stop

Could flick-scrolling be implemented as a feature, and save us all from RSI? 😅
