Add a button front end to add friend


I think this plugin could be great for me. But I have two questions.

1. Can I add a button/link on the front end that let’s a user who visits another user’s site click that to be friends?

2. Is it possible to have a page on the frontend that a user can go to and see the latest activity from the friend list? Latest post from all friends for example. Sort of like a query_posts but with a friends argument.
