I'm not sure where we're supoosed to put our early release feedback. Is this the right place?
I put a post in feature requests
http://forum.cakewalk.com/20165-Color-selection-m3421513.aspx#3421513 I love tungsten too - and there are some colors you can change, and some where the changes have no affect. I wonder if it would be possible to come up with a list of what color settings still work (like audio track text color, midi track text, markers etc) and which don't work (folder text color).
I know it would be a pain to actually change the whole (color preferences) interface - and different things might (not) work for different themes. I bet we could come up with a "unofficial" list though ;-)
