I am afraid that all implementations which use Kitodo.Presentation currently show the problems which I have described above. Maybe we can add examples of better user interfaces from other libraries here as an inspiration for Kitodo.

I completely agree with the proposal to make the page view more accessible and user friendly, but I don't think this requires changing the underlying framework. OpenLayers already offers all the features we need including support for touchscreens/touchpads, responsive designs, restricting zoom levels according to image resolutions, always keeping the image inside the viewport, etc. In fact, support for touchscreens and responsive designs are already implemented in Kitodo.Presentation - the issue here is that most instances of Kitodo.Presentation don't restrict touch input exclusively to the page view, leading to an awkward experience where for example pinch-zooming not only zooms the page image, but also the surrounding layout resulting in seemingly uncontrolled zooming jumping between different zoom levels.

I suggest keeping OpenLayers, but improving its integration with Kitodo.Presentation in order to address the usability issues.
