Change icon for confidential issues
Description
It was decided in #20960 (closed) that the current icon for confidential issues (fa-eye-slash
) should be used for the Unsubscribe action, so we need to find a new icon for confidential issues.
Proposal
Original Proposal
I propose we use the same icon we do for Private projects (fa-lock). Both uses have a similar meaning and it is a clear symbol.
