In previous versions of Mac Reader, the blue info banner "This file claims compliance with the PDF/A standard and has been opened read-only to prevent modification" could be dismissed without side-effects by clicking on the circled-i symbol. In the otherwise much improved 2023.008 version, this useful capability has unfortunately been lost. That banner is an irritating waste of valuable screen space (for people like me who spend long hours doing research in PDF/A files) and should either go away automatically after a few seconds, or be dismissible as it was before.
