That is looking Sweeeeeeeeeeet!

To each his own.... I don't like the new darker look of most new software. I like the current Sonar because it is bright and I can see everything well. (well....except for the plug-in enable/disable issue)

Indeed. I'm fairly comfortable with it at this point but always interested in options. My understanding is that this update, when it drops, will provide fairly deep and comprehensive theming/skinning for the whole program, but won't force anyone to change anything. The dark theme that has everyone excited (I think it looks pretty good myself) is the only one that has been teased so far, to my knowledge, but I would imagine that if they're going to the trouble of overhauling the front end to that degree, there will be more than one new theme provided on release... and, of course, more to follow as people tweak and share. 

What makes me go on board in the hype train is the chance, to combine different schemes across the DAW (some mix up with the dark theme and gray or White one for example) but well we don't know if we have this modularity in this or future update.

I'm all for this one posted on March 28. Tho it looks photoshopped, it shows how good Sonar can look if cleaned up a little.
 

Wow, that dark with orange looks fantastic!

This is THE Sonar update I am looking most forward to. I wish we knew when it was going to be released.

You know, I realize that one of the things I like about Mixbus is the UI. I've learned to live with the UI in Sonar even though I'm not crazy about it. I've come back to this thread a few times JUST TO LOOK AT THAT GREY/ORANGE theme. Seriously. A good UI update would be most welcome.

Ditto. But being able to switch to a different theme for a change of mood is nice. I'll probably use this new dark theme only occasionally. It looks too loud and busy, so either my eyes will get tired or I won't be able to concentrate anymore after working in it for some ten minutes (or less). That's what happened when I tried darker colors in Studio One 3.  

Will be sticking in the default. This one might be good for some occasional try. 

With my color deficiency, ANY extra choices would be most welcome.  That orange and dark are very easy on my eyes.  It would be nice if you could go into a "Color Edit Mode" that leaves what you have on the screen and you could click and pick what items you want to change.  The current system is a lot of trial and error.
