Slick design but flaws in ergonomy...

... with a major mishap: no support of bluetooth keyboards.
Keystrokes work to type text in an active box, but no support of arrows to navigate the maps, nor of any shortcut to create children or sibblings boxes. Too bad, as it would have allowed to really start creating and editing maps on iPads and iPhones.
So far, only the web/desktop interface allows serious editing.
