Please put back Show options button!

Please, please, please put back the Options Button Visibility section with the Show Options Button toggle that was formerly in the iPad Settings under Proloquo2go. My kids can be locked in Proloquo2go with Guided Access but now that I upgraded to Version 4.1 that feature is missing. Without the ability to hide the Options button on the lower bar of the Proloquo2go screen, my non-verbal Autustic kids are getting into all the settings and messing up their boards, icons, everything! Can you fix this ASAP? Thank you.
