When I am viewing music, there is a little slider on the bottom of the screen which shows me a line and a dot, the dot tells me how far along I am, line the fourth number of a 10 number set.  

In landscape mode, it blocks my view of the bottom of the page.
I'd like to move it or turn it off.

I'd also like to know how to turn the 1/2-page viewer on and off.

thanks
