xProp is a simple Google Workspace™ addon that allows the user to manage extended
properties on calendar events. Private and shared properties are both accessible.
Users can manage extended properties on event instances or recurring events.
In its current state, it's a pet project put together to fill a niche in the Google
Calendar™ online toolset. While extended properties are more likely to be accessed
by a backend service, this gives manual access to any and all properties for
granular manipulation or debugging.
I will consider adding to its functionality, as people find use in this tool.
