- Then on first run, go into options > editor > colors, and change 
whatever color you like. (e.g. background or gutter). well ok that is 
only the editor windows. It will not affect breakpoints, etc....
- The main IDE bar has/has not the word "debugging" in it.
- You can also have a different projects open. As the last open project 
will be re-open, and that is stored in primary conf. With that, the 
debugged IDE will not open the stack and watches window (unless you want 
it to).
