Does not work for me.

Clicking on adding contact, does display a form to enter contact details bit clicking confirm does not do anything.

Removing contact seems to be not doing anything either.

Implemented subscription request handling.

This issue is related to using more concurrent connections to server than allowed in server configuration

Adding new contact to the roster works very well, there is no removing contact function yet and no editing of existing contact.

The only, real problem, however, is if you enter only user JID and leave other fields blank, the contact name is empty on the list, it should display user's JID in such a case.

To sum it up. I think it is good enough for the One launch.

Use right mouse button on contact in roster to see additional functions other than Add contact.

Ah, that did not cross my mind. Excellent. Works perfectly.
