I liked the idea of a dark flat theme, but had to revert to Mercury. There's more to design then just staying trendy, you know.
No track colouring is a showstopper.
My eyes also hurt from too much contrast and complete lack of borders given the amount of buttons and other controls. Especially since many are amber-lighted or has scarlet red in them. Would be nice to change at least this amber colour to Photoshop grey, Mercury blue, or Artist green.
There's also some colour inconsistency: the bluish whites of the text in the transport bar vs snow whites of the font in the control surface bar.
Overall I also would like to darken the whites.
And selected track highlighting has always been a problem. Doesn't work at all in Mercury. And is too subtle in Tungsten.
I think the theme has a great potential as long as the above issues are addressed.
