The only crucial feature missing is backup and restore functionality. If your phone is bricked you are toast. Additionally there is no way to transfer the tokens to a new phone. The only way to achieve this is to use an application like Titanium Backup to backup the entire application. However this requires root privileges. A pin security option would be nice as well."
