They say motion editor is back with Flash Pro CC 2014 so I installed the trial version but I can't find it anyware.
Flash Pro CC 2014 (v 126.96.36.199) is now available for download via the Creative Cloud App.
We have included an all new Motion Editor along with several other new features with this release of Flash Pro. The new Motion Editor is completely redesigned, intuitive and easy to use while preserving the core functionalities and backward compatibility with Flash CS6
To Invoke the Motion Editor, simply Double-Click on your Motion Tween span on Timeline (or Right-Click and select 'Refine Motion') and the Motion Editor opens up in-context in the Timeline itself. Double-Click again to collapse once you have made your adjustments.
