Yep, thanks for fixing the unreadable blue interface that's been giving me headaches for the last few months.
In my opinion there should be an option to change it back to yellow. But i got used to the blue one.
I won't be able to upgrade for another couple of weeks, but I want to say how delighted I am to see Adobe focus almost exclusively on bug fixes in this release (and not just of Premiere, but of Speedgrade and Audition, too).
So thank you, Adobe! Fixing the many problems with CC 2014 is so much more critical at this point than adding new features, and I don't think software companies in general make the decision to prioritize bugs over features often enough.
We know that some people are still having a hard time seeing the UI, but we have some changes in mind that might take some time to implement. I ask for patience in this regard. FWIW, the latest version of Premiere Pro has a fix for the blue UI in the Effect Controls panel. Bezier curves for keyframes are now much more visible.
