Sorry, but I can't work in Tungsten. I simply don't see anything. It looks similar to Sonar pre-skylight with tons of toolbar buttons. Here come the comparison pics.
http://imgur.com/a/vk15u The cluttered track controls and control bar, lack of track colours, lack of borders and sections - all that render it completely unusable for me. All I see in the console are meters and the top relatively clean part. Everything else is a decorated new-year-tree LED-like mess. And those laser red dots everywhere instead of Arm for record markers. The FX Bins in the pro-channel are still blue by the way.
Overall, Mercury is sure not ideal, too, but I can at least work in it.
And yes, I agree, SONAR needs an ARTIST. And the SkyLight needs a rework too, with attention to CONSISTENCY with actual use cases, not just in colours among all elements.
