As a new or average Qt developer I need to see both the Help pane and Edit pane so that I can for example see both the getting started tutorial and the code I'm creating from the tutorial.

More generally it should be possible to have one Mode in one window and another mode in a second window.

These days most developers (myself included) run with two screens. I could have the help text filling one screen, and the edit text filling another which would provide a very comfortable development environment.
