keyboard focus when adding a contact
1. Create a contact group
2. Click …
3. Click "Add a contact to this group"
Observe that keyboard focus is lost. Instead, it should be transferred to the "Type a name" filed in the modal dialog that appears.

Also when you've added a contact, instead of using mouse enter key must activate add button.
Also please provide adding multiple contacts at once, or support adding office groups directly.
