As an Admin, I want to be able to publish organization-wide announcements and updates within Port, visible to everyone. It would be helpful to categorize messages by type (e.g., Critical, Informational) for greater visibility and urgency. Additionally, it would be valuable to have the option to customize the recipients of these announcements, targeting specific teams, roles, or even individual users. This would allow us to send tailored messages to specific audiences when necessary, prompting them to take specific actions or providing them with targeted information.

In addition to the banner feature proposed by David, this capability would allow us to communicate new (organization-specific) developments and other important information directly within Port. This ensures everyone stays informed without having to rely on external communication channels.

that would be great to have the ability for users to click "acknowledge" button for that kind of notifications.
