Our mobile client has its own versioning and so far this app is free. We haven't decided yet what licensing model we are going to use for it when we add more significant features to the client (namely, the full-fledged address book). There are different options that we are considering.
The lack of this feature almost makes the Android app unusable. Without an address book, I find it almost impossible to keep up with 20+ client machines. Can the implementation of this feature be upgraded to a higher priority please?
