Improvements have been made to the Preview Data section so that user enrollments can be viewed in a manner which is more human-readable.
Clicking on any of the rows in Users will slide in a side menu which shows all of the users' enrollments.
The side menu will contain the user's sourcedId, his/her name, the org that he belongs to, which grade he/she is in, and what enrollment data the user has. You would be able to use this data to quickly check which classes a student is enrolled in, without having to find the student's sourcedId and perform a search using the Find feature.
Clicking on any row in Classes will bring out a side menu with more information about that class.
The side menu contains the sourcedId of the class, the class title, the org that class belongs to, the grade that it's taught at, the teachers of that class, and the students attending. This allows you to quickly check class rosters to see if a particular class does not have either students or teachers.
