As it isn't possible to comment on the post itself, a few observations:

SHIELD-9335 (unsubscribe button for notification emails)

Will there be any analytics on this so we can see if people are unsubscribing? Please ensure that the wording is clear enough that we don't get people unsubscribing from all announcements thinking they are just unsubscribing to a single course!

NTNGL-3023 (Third party data into Analytics builder)

Please consider adding Anthology Ally's API as a supported data source

BORG-3800 - TabId in quiz logs

Sounds interesting - I hope it's presented with enough context to prevent amateur Sherlocks jumping to the wrong conclusions and making unfounded allegations!
