Feature request: trigger event "metadata-menu:class-assigned" and "metadata-menu:class-unassigned"

[msageryd]

In order to build more automations upon metadata-menu it would be of great help to have events triggered when a class is assigned or unassigned. Maybe such events already exists?

Event name suggestions:
metadata-menu:class-assigned
metadata-menu:class-unassigned

Currently I havent found a way to identify the class of a note if the class is assigned via a tag. If the class is exclicitly assigned I can find the class in frontmatter, but not if the class is derived from a tag. Having events for this would be awesome.
