The title just about says it all.
For example, when you open an app it wont appear on the touchbar dock widget until another app is opened, triggering to widget to refresh. When the app is quit, the icon will stay there until another app is open or quit to trigger a refresh.
I'm guessing this could be fixed by telling the widget to refresh after a short delay so the newest event is incorporated into the widget's information. I tried using a manual applescript widget refresh to no avail. If anyone else has had this problem and figured out a good solution please let me know!
