Much as linking/importing email to Agenda is a valuable tool, I know that linking contacts from the Contacts app would be extremely useful. I’m sure many others have people/organizations that they are making notes where they are related to a specific person, group of people, and or orgainzations.
At this time, I can drop a vCard into Agenda. That is okay, but the behavior is not. If I drop a vCard into Agenda, the behavior I expect when I click on that attachment is either opening the contact card in the Contacts app, or showing me the contents of the Contacts card. What I don’t expect is for it to attempt to import the card back into Contacts.
As pointed out in another thread, every project we do now has been on the roadmap since 2018. People request things very quickly, but each project is a lot of work. We pick what we think is most needed at any point in time. Contact integration is something we are still planning to add.
