+1 for this, since NZB360 already has Headphones support, it should get lidarr support also. I suspect it's going to be a while until it's out of beta though.
Liking the look of LIDARR.

Seems to be being updated regularly and using the Sonarr 3.0 UI if I'm not mistaken.

Would like to see this added to NZB 360 as well, as it appears to be much better than Headphones, as Radarr was/is better than CouchPotato.
