One thing that I really liked about this wallet was the easy to manage addressbook. At the moment I have an address in my wallet that totally breaks the app, it is completly unusable. Before I could create a new address, send all my coins to there and remove the broken one but that whole option is gone. Is there by chance any way to fix this problem?

If this downgrade is to stay, I have no choice left but switching to another app to manage my funds. I understand that it isn't encouraged to use the same address over and over again, but for normal users like me this isn't a big deal and removing this option is a really bad choice.
