When designing Loopy Pro pages which are exclusively MIDI control surfaces then it would be useful to be able to temporarily hide one or both of the header and footer page elements. This frees up screen real estate and makes the control surface look more professional. I know you can swipe away the footer elements but the space is not reclaimed.
My Atom Arranger layout at GitHub MisplacedDevelopment/AtomArranger, for example, tries to keep a navigation page out of the way at the top of the screen, but the footer causes the page to encroach on the AUM elements below.
Thanks!
