Thanks Lee. It's actually a new feature, which is that you can mail, delete and open pages from other applications in MIDI Designer 1.5. Sending pages is amazingly convenient, as we've already been seeing in the Beta. I was hoping to get 1.5 submitted by this past Friday, but some late-breaking issues need to be handled. Since MIDI Designer is a professional app and being used in performance situations around the world, bug-free releases are essential.
Anyway, I wanted to mention that you can delete pages via iTunes if your device is connected.
Best and thanks again!
Dan
