I was having a problem with codesigning my apps, so I deleted all the keys from the keychain. Then I went to Certificate Assistant => Request a certificate from a Certif
Okay the name that shows displays the item you highlighted in the Keychain mainwindow (if you select a different item here you also see the menu item change with it). If you go the the category section on the left and select my certificates for instance and go back to the certificate assistent menu item it looks/acts like you're used to. Hope this helps!
