It would be nice and helpful if, for kodi built-in commands,
either additional callbacks or additional
onNotifications can be added to the python Monitor class

The ones in question

exportLibrary
RunAddon
RunAppleScript
RunPlugin
RunScript

Events when action starts and stops would be needed.
To make this failsafe, it might be considered to return
an unique id on built-in command execution and within callbacks/notifications.
In case multiple RunAddons are requested this id
could be used to find out which event belongs to which action.

Thank you for considering it.
