When clicking a button on the index card in the reference map, highlight / zoom in on the reference in the reference map graph view

[MKDJr]

Is your feature request related to a problem? Please describe.
I would like to be able to quickly zoom in or focus on a specific reference in the reference map graph view via selecting a card (or clicking a button on a card) rather than panning across the graph in search of the reference.

Describe the solution you'd like
When clicking a button on the index card in the reference map, highlight / zoom in on the reference in the reference map graph view. Maybe:

• 2nd+ degree references fade out,
• 2nd+ degree references are hidden, or
• the view zooms in on the reference and its direct connections.

P.S. Thanks for the amazing plugin!
