Offline pager and classic viewver zoom improvement

[Former user]

Dev , i find that u have provided too much zoom and also that tp change a page u have to first exit the zoom. So plz make it so rhat we can change pages without exiting zoom view and also plz page loading take lots of time while image scrolling is not smooth . In comparison perfect viewer or challenger viewer are both better alternative but i would like to use the inbuilt viewer so plz if u can improve it plz do so. Thanks
