Begin of the insertion* When writing a comment, if "Restricted visibility" is checked, there is a link that lets the user view _who_ can view these restricted-visibility comments.

* This will take the user to the Members page of that project with the 'View comments with restricted visibility' permission filter enabled.

* This page does not yet exist, we'll create a ticket for it.

* On a restricted visibility comment on the Activity stream:

* Hovering on the lock icon (on non-mobile screens) should display a tooltip: "Only visible to certain members. Click for more info."

* Clicking on this lock icon will take the user to the Members page of that project with the 'View restricted visibility comment' permission filter enabled.

* The "Show everything" view filter on the top right has two additional options:

* "Restricted visibility comments only"

* "Show everything publicly visible"

* The ability to specify a custom scope per confidential note (eg. selecting individual users or groups)

* Notifications that adapt to a change in role where you no longer have the permissions to view restricted visibility comments:

* If the notification is aggregated,

* Keep the notification, but remove those updates that are no longer relevant

* If the notification is singular (only for restricted comments)

* Hide the notification entirelyEnd of the insertion
