[FEATURE] User, session and temp variables not shown in preview

[ptrckbp]

Right now, the user, session and temp are hidden variables, that require know-how to be used.

The preview should include user, temp, session with explanations. I realize getting the list of all possible values would be difficult due to actions / hooks updating the object dynamically, but having them in the main list would help with understanding the application.
Something like this could be used for the preview :

User : parent object containing cross-session variables
Session : parent object for session variables
Temp : parent object for flow-specific variables

This is not a bug it's a feature request.
Thank you for filing this .
