If you hit space bar to bring up the command selector and hit Edit In Game, you should get a view that shows you all the debug draw, gizmos, etc. Hopefully this answers what you're referring to.
oh wow that's perfect! In fact, this does something a little extra I wish Unity could do - because I can play the edit scene and game scene side by side, I can modify experimental properties at runtime, then copy+paste them into the edit scene on the fly (in Unity it's a lot of copy+paste into notepad, stopping the game and hoping you didn't forget anything and pasting back in).
