When admins block workspaces (e.g. when desks are equipped with new hardware), it would be nice if you could put a comment like "Desks are getting equipped. You can book these desks again tomorrow". This comment could appear on the floorplan (by default or by hover over those desks) or next to the desk names in booking grid etc.

This would bring more transparency for all users and they would know for which reason and how long desks are closed.
