The most important objective for a world creation tool must be to allow the designer to see the world he is creating while simultaneously enabling him to make modifications to it. (WYSIWYG)

The designer should be easily able to move the camera in this player’s view
This movement is probably best accomplished with a simple “flight” mode

7. Desired Functionality Visualizing the Level
Of course, the world as it will appear in the game is not always the best view from which to edit that world. For this reason, level editors often need to include an “editing view” in addition to the player’s view.
