Organizing / Arranging Friends on Beta Client

It has been difficult for me to move friends into different groups. For example, I click drag and hold to move someone and the groups start dancing around and I can't get them to stop dancing. (I add a lot of people) Sometimes I accidently move friends into other groups without knowing. This hasn't happened to me on legacy often as I do now, and if I did do it, it was a lot easier to see where they went.
