I have to say i did like the look and feel of the new UI, however i had some issues with testing new accounts against unidentified machines - testing a new account would never succeed or finish and i had no way but a refresh to abort it from trying, i was also unable to view/edit http accounts, it never displayed - all others did though but since the RC came out and i moved to that all the issues i had have now gone again
I also had a weird quirk where a machine that was identified for some reason became unknown and on next scan it showed up as a wireless device - and not a PC with wireless, i removed the device and a fresh scan found it but i cant explain why my device type changed from PC to wireless device.
Hopefully the full release will be out soon and i can move on to testing/using that in production.
