Thank you for this Dan very helpful and so many times I have wanted something like this and had hit and miss results with 3rd party plug-ins that end up not showing up on other computers that I have Keyboard Maestro installed on at a later date.
You have so many things that enhance Keyboard Maestro I hope you and Peter can work more together directly.
Also thought I would link to your other notificaiton plug-in you made if it is still relevant.
