About the new features

There should be a way to remove friends. A small "x" nest to the name should do it. Also, for the loan area, a place for date due might also be a nice addition.

Should it be a two way removal e.g. I remove someone and that person also doesn't have me on his list?

I think due date unneeded as it's just loans between friends.

When you remove someone there could be a notification of removal that lasts a set time period (like a week) or until the friend to be removed acknowledges the removal.
