I seem to recall people asking for a notepad feature, customized checklists, etc.  Would it be possible to have an optional instrument or perhaps several with different names/functions?
This instrument would be named "Notepad", "Checklist", "Whatever else might be asked for"  If we touched this insturment it would start a mini program that would Exit Application while still having it Run in Background,(Like when we touch Menu>Exit Application>Run in Background) then launch the notepad program, or launch a specific file (Checklist.txt) that would be run by the notepad program.  In the notepad program (if the iFly team can mess with those programs) add a button that would re-activate the iFly navigation program.  If they can't add the button, we'd simply exit out and press the iFly icon displayed with the other Five options.
