+1 as well.
For now, I've been able to create a somewhat workable solution using the Shortcuts app. What I've done is create a shortcut with the URL to open indigotouch to my main page with no nav bar followed by Open URLs command. Then I make a home icon for the shortcut on the home screen. When I tap the icon, I get a short transition to shortcuts application followed by opening of indigo touch on the page I want without the nav bar.
It works, but there are two problems with it. First is the initial flicker of the screen as it transitions through the shortcut app, then if I move away from indigo touch and come back, the nav bar comes back

If it stayed until indigo touch was restarted, that would work better for me.
For my wall mounted ipads, I also engage guided access to make sure that indigo touch is always running. This avoids both problems there.
