Image fit width zoom
Image fit width is wonderful but I want to pinch to zoom on it
Maybe another similar suggestion would be, when fit image to width is turned on, that we would have ability to open image in full screen mode (there you could zoom-in ever more). Currently there is only option to save image.
I'd even be happy if the non-fit-to-width mode would let me zoom out. It lets me pinch to zoom in, but not out. On the phone, it's really important for useability
