1-click call/chat to discuss an item

Often, during shopping, a clarification/discussion about an item is required (e.g. to discuss alternatives to the original item, to choose among available options, etc.). It often happens multiple time during a shopping trip. It would be very helpful to have shortcut buttons to do one of the follownig:

1. Open the phone dialer. Possibly, have 1 phone number stored in the settings and directly call it (e.g. I'll have my wife number there).

2. Open a favorite chat problem - whatsapp, skype, handgout, etc.

3. "Share" - will allow to send a text message, or possibly some of the above options, with a specific item.
