I just noticed this while writing a reply on the Keyboard Maestro forum.
Item 2 below is written:
2. It seems that I don't have to specifically exclude background apps (e.g., Dropbox, Hazel, Alfred, etc.). It appears that those continue to run. Is that the expected behavior?
It is clearly prefixed with a “2. ”, but Discourse is changing it to a “1. ”.
Specify exactly what apps are failing to quit.
