The fact that webdetails joined pentaho doesn't mean we'll stop doing work on the Ctools. Much on the contrary, not only we're doing more work than before, we're also in a better position to do that work in a more aligned way to the main Pentaho roadmap.
As many of you know, Pentaho 5.0 is almost out, and comes with a different look and feel. And to start building some coherency, we changed CDE's look and feel.
This is just a start; In the backend, lots of stuff is happening / being planned to try to improve the ctools feature-wise. But it's an amazing step!
It's already available in the dev branch, and will make it's way into stable. Please report any issues you find.
Thanks to the UX and dev team for pulling this one out!
