p.s. if developers will read this thread... you can also use "long taps" for other actions.
1 sec zoom tap -- zooming, 5sec zoom tap --- zoomout.
1 sec next tap -- next page, 5 sec next tap -- 10 page forward.
1 sec wheel tap -- display ROTATION (hope we will see it) , 5 sec tap -- software picker.
Or something like that.
