Pictures in Contacts
 

I notice that I can now save an image with a Contact.

Previously this used to be limited to published gravatar images, but I can now save an image directly - similar to how Google contacts works.

Yes, this feature has been there for a few weeks. If I remember correctly, it was added around the same time as the new sidebar features. Other features on the Contacts page include:

• Buttons at the top to call, sent a text message, compose an email, or send a calendar invitation to a contact (depending on the platform supporting calling and texting).
• Click the icons adjacent (on the left) to the email(s), phone number(s), or address(es) and you will get several additional features, including displaying the data in a very large font, copying the data to the clipboard, displaying a map of the address for that contact, or showing the directions to the address.
• Display of the three most recent email messages to/from that contact, and a button to quickly find all conversations with that contact (in conversation mode).
• Display of future calendar events associated with this contact.
