Calling address book contacts in Skype 4

I've just updated to the new Skype 4 on my Nexus 4. I regularly use Skype to call numbers saved in my phone's address book contacts, but can't find where to do this in the new version. The previous version of Skype 3.2 had an address book icon at the top right () but this is missing in the new Skype 4 (). Is there no longer a way to call my phone's address book contacts without adding them as a Skype contact as well? I'd rather not set Skype to sync my contacts as I regularly jump back and forth between personal & work accounts.
