For example, can I remove some of the existing functions from the UI (such as print)

In addition, every time I call the Cordova module's get page number js plugin, it only works the first time, any subsequent calls return still the first number.
For example, if I open a doc at page 3, get page number shows me 3, but after that would cause all future doc opening to have the page number 3 when calling getpagenumber.
