It's hard for humans to keep track of our wallet activity when a .jpg avatar is not present. How about an option to label addresses with a tag or alias so we can easily see who we transacted with in the activity?

This comes from a real-world example when my team and I send tokens and ETH to each other. I have to go to facebook/line/kik/gmail to see which address belongs to who.

I'm not advocating a full address book, but just a tag on the address in the interface.
