Android Mobile App: Show a single part only

I use Musescore on my Android tablet to display sheet music from musescore.com.

As far as I have been able to work out, the Android app offers two ways to display the score:
1. Full score in portrait mode (i.e. every part as per the conductor's score), or
2. Single instrument in landscape mode, with only a few bars shown and with the score rapidly scrolling past.

For playing a single instrument, I find both view modes very difficult to read.

Please implement a way to display a single instrument's score the same as a traditional page of sheet music. Auto scrolling the page would be nice, but not essential - a big "page turn" button at the bottom of the screen would be fine.
