Allow for a Favourites Contacts view like you have on a smart phone

[vanessahunt]

We like the Call feature where you can call a Contact direct from HubSpot. However, most smart phones have a 'Favourites' option where you can call contacts direct from that list. It would be great to have an equivalent feature in the HubSpot app, where you could then call Contacts from your Hubspot filter view easily. Obviously my Favourites are different to your Favourites, so I can't use a simple contact property as a criterion.
