It would be nice to see Key Editor changes dynamicallywhile they are being made - or edit a keyframe directly in the view window - rather than needing to close the Key Editor before you can see what you've changed.
While using Creo Illustrate 5.1 the program had a glitch and crashed. When I reopened the illustrate file, I saw that the path for a pair of pliers was correct, but the orientation was now wrong. The only way I could change the orientation at a specific keyframe was by right clicking on it and opening the Key Editor. This gave me the ability to change the position and orientation at that specific keyframe -- however the preview window did not update until I closed the Key Editor dialog box. Please see attached screen-shot.
