Is there a way to make the Xcode text editor show all white space? I am mostly interested in the big three: spaces, tabs, returns. The setting View->Text->"show space" works, but the setting View->Text->"show control characters" seems to do nothing at all. Also, why do these two settings get reset when I close and reopen Xcode? I am using Xcode 3.2.3. Thank you for your help.
