Nice features! Thank you!
So quaternions will come with the next update I hope. We need them against gimbal lock.

What about the interactivity with Popcorn fx?

Lock Selected / Unlock Selected / Unlock All Keyframes

Three new features have been added to the right-click context menu for the Curve Editor > Outliner. 

• Lock Selection will grey out selected curve(s) making them unselectable inside the graph view.
• Unlock Selection will remove the lock placed on the selected curve(s).
• Unlock All can be used to remove the lock from all of the curves inside the Outliner, this can be useful when unlocking disparate curves becomes cumbersome. 

*All of these functions support multiple selections.

Editing Path Position

The speed at which the path constrained object travels in its set trajectory can be adjusted via Curve Editor > Outliner > Constraint > Path Position (%).
Animating the Path Position can slow and speed up the progress down the track of the path adding tension and rhythm to the path motion.

Finding Path Data in Curve Editor

Curve Editor can now edit Path Position and Offset and there are two ways to find this data:

1. Right-click on a path constrained item in the scene and select Curve Editor > Constraint to open the Curve Editor along with the object's path data set.
2. Go to Edit > Constraint inside the Curve Editor panel.
