I have noticed that Presentation mode, while useful, and while there are enhancements planned to be able to define more than one presentation, is much more rigid and inflexible than the "Outline" mode in Mural.ly.
Quite frankly, I like SO MANY things about RealtimeBoard MUCH MUCH more than Mural.ly, I want to congratulate you for making RealtimeBoard such a highly productive and efficient an WONDERFULLY INNOVATIVE product to use.
If you look at how the OUTLINE mode/LayoutViews work in Mural.ly, I think you will see that it is a very efficient way to navigate a Board. Mural.ly Outline layout boxes/views work very similar to how the RTB Presentation boxes work, with one exception. There is a visual hierarchical Outline that can be navigated while NOT in presentation mode. This makes it powerful to leverage while NOT in presentation mode. While editing you can click on an Outline box name (similar to a RTB Presentation box number) and when you select it in edit mode the view zooms/pans to that view.
Ironically, the vast navigational flexibility of how "Outline" views work in Mural.ly and how they allow you to quickly navigate around the Board would have more logically been created by the RealtimeBoard team since RTB is a more infinite canvas.
I urge the RealtimeBoard team to adapt your Presentation mode into a hybrid navigation capability like Mural.ly has done with Outlines. It would make RealtimeBoard dramatically more easy to navigate.
