Multitouch Trackpad Supoort
Trackpad (MacBook, Magic Trackpad) Support for paning around with two fingers and rotating with two-fingers-gestures.
Definitely something we want to add support for!
Pinch to Zoom; two-finger panning and rotating; momentum when viewing, not just stopping abruptly when fingers leave the trackpad.
macOS Native Fullscreen support, NOT just expanding the window.
