Expected behavior
Users can select and send multiple vCards at once, similar to sending images.
Actual behavior
It is not possible to select and send multiple vCards.
Explanation
Sending vCards is a very useful feature. Often, you want to share more than one contact this way. In my opinion, it would therefore be useful if multiple vCards could be sent at once.
Furthermore, some users use groups to manage contacts. This feature would also make it easier for them to send vCards to these groups.
