Unfortunately, the goals of a video game are not similar to the goals of learning to use and using an editor. The only thing you gain from not having all tools immediately available at your disposal/discoverable is frustration because you're still in the editor and not done editing. Game playing is a task unto itself, editing is a means to an end.
