I think this should be a overall comment that users can uncomment if they want this change.

Hi guys I have no feelings on this.

@iton0 Can you help me understand why you think this should just be optional?

Do you use/do other people use different conditional break symbols?

[iton0]

I appreciate the overall addition, but I wanted to make it optional for caution's sake. This way, users can experience the default debugging setup first and choose to add features if they wish, rather than having to remove anything.

Ah I failed to notice it's already commented out. merging!
