I think it would be great if either your friends list was there when you make a buddy read or if the username search was refined so that if you put in a part of their username it will find the right person easier because you're their friend.

For example, whenever I add my friend ally to a buddy read, I always forget her actual username, so I search ally but it doesn't come up with the possible options, so I have to go to my friends tab and find what numbers she has after her name in her actual username before I can add her to the buddy read.
