Wendy,

I'm not sure I fully understand the problems you are facing, but I'll do my best to explain things. First, the floating toolbar at the bottom right of the library screen would serve no purpose once a song is loaded. It has buttons for going back or forward on the library screen, a toggle for performance mode, and a toggle for the filters. The quick action bar at the bottom right corner of the screen when you have a song loaded is meant to be used to quickly access features. You can long press the metronome to view the metronome settings, or tap the metronome icon to start/stop playback. If you don't like the quick action box, you can disable it under Settings->Touch & Pedal Settings->Touch Actions. It sounds to me like you may have performance mode enabled. Tap the "lock" icon in the floating toolbar at the bottom right corner of the library screen or the center of the quick action box to disable performance mode. Then you can tap in the center of a score to bring up the song overlay. From there, you can access the song display settings at the bottom of the overlay.

Thanks, Mike. I think as I get a little more intrepid, I click some buttons and don't figure out what they have done. I'm pretty sure you are right being locked into performance mode and not remembering how that got set. I also wonder whether the overlay has always been across the whole bottom of the page, and I never looked at the buttons on the left. I did not know about long-clicking the metronome on the quick action bar. I have turned off the page slider now and the overlay still comes up, so it was possibly only a co-incidence that the overlay came up when I turned on the page slider.

This seems very easy now, even to the extent that my two-page-in-landscape stays set (and thanks again to @schnautza for the explanation).This is a WONDERFUL feature. I'm so glad you implemented it.
