I'm not sure what you mean by your question about where to choose zooming with two fingers. The pinch gesture is the only way to zoom at the moment. If you open the song overlay, tap the second icon at the bottom left and then Zoom/Pan Settings, you can change some zoom-related settings there, such as whether zooming is saved in the database or not. 

What I meant earlier is that I thought that there was a choice for how to zoom, duh, nevermind.

But I don't see zoom/pan setting item in the display menu ...
