Performance improvement request - Loading Apps vs Pages

Appreciate the input @Jeff_Hager and @Darren_Murphy. I did install the 3Dethos on my iPhone (Darren, thanks for sharing!) and it brought up one follow up question:

On Darren’s Pages project, the project’s menu is displayed across the top as tabs in landscape view (like it is on desktop). In portrait view, the Pages project menu is displayed across the bottom as app tabs. Does Pages have a setting/feature that allows tabs to be tucked into a hamburger menu in the upper left corner in portrait view on mobile viewports? Thx
