Associate cards with one another
I have a “Payment: SlickVPN” card and a “Service: SlickVPN” card. Obviously, these two cards are related to one another but they contain different types of information. Therefore, it would be handy to have the option to associate them with one another so I can easily skip between them. Another example would be configuration cards I have for Apps on my iPhone and the configuration card for my iPhone, or a user account card and a domain card, etc.
