What does the "Markup" extension do (?
What type of file would the "Add People" extension work on (I tried with a vcf)?

Im talking about system extensions (System Presfs/ Extensions), not file extensions

.VCF is usually a contact card / file - can be opened with most email clients

Edit - sorry same mistake - markup is the edit mode in preview ( if I understand this time)
