I do not want Script Debugger to resume focus, I do not want a Notification… I am smart enough to determine if the script has finished or not… how do I turn off all this noise that truly distracts from real issues… notifications are unacceptable as a routine UI feature
The notifications can be less obtrusive if you set them to “Banner” in System Settings. Then they’ll dismiss themselves automatically after a moment, saving you from having to click them away. Or you can turn them off altogether — I think errors are reported with a dialog rather than a notification?
But I don’t think SD should be stealing focus when a script completes, unless you have “Bring Script Debugger to foreground when scripts end” enabled in Settings. It doesn’t put up a notification in that case, but I’d find it a lot more annoying than the banners. 
If you’re not aware, the developers are retiring Script Debugger in a few months, so I don’t know if they’re still considering feature requests at this point.
Go to Preferences/Settings -> Execution and set your preferences accordingly.
