(Android) Pause / Resume RZX request. Some sound crackle.

Hi, is it possible to add a Pause/Resume button (in Android version) so no menus come up on the screen ? I wanted this for watching RZX replays of text adventures, sometimes it continues too fast so i'd like to pause the screen (with no menu's appearing) so I can read the text before resuming.

I also notice some slight sound crackle in emulation.
