Previewing pictures imbedded in books is not prefect
Reading experience is great, but zooming on the pictures imbedded in the books is a little problematic. You can’t press on the picture to zoom in which is a very natural and common way of doing so in many apps, you have to pinch it to the enter the zoomed in preview mode. To exit you can’t just pull it Al the way down as a normal way of exiting such a mode, but you have to manually press X to close the picture. It is a pretty big deal when you are reading a handbook with a lot of screenshots/pictures that show you examples that you need to zoom in to see properly.
