It simply didn’t work...
… or it is under documented and non intuitive. I tried to create a board. Included stuff. Stuff wouldn’t open necessarily as supposed. Or they would, sometimes. Unreliable, at least. I love the idea (if I did understand it): you have the elements of a presentation all visible in one screen and then you open them when you need them, allowing to non linear presentations. Sounds cool, but I simply couldn’t make it work after about half an hour of work. And I don’t belive in applications that take more than half an hour to present themselves to the user at least in their most basic functionality. Not in 2015. Sorry, uninstalling.
