Hi all, Here is a list of new features that will be available in the Animation Window in the upcoming 5.5 beta. Performance improvements We tremendously improved the rendering speed for both the Curve Editor and the Dopesheet Editor in the Animation Window. We mostly worked with baked/dense animation data to make sure the animation window would behave as expected. While it's difficult to really benchmark those improvements, we think they will ease out most of the pain users had with the animation window performances until now. New Clamped-Auto tangent mode We added the Clamped-Auto tangent mode in an effort to replace the current Auto tangent mode which has a tendency to create curve overshoots when keyframes are near one another. The Clamped-Auto tangent mode gradually becomes a flat tangent instead when a keyframe goes out of bounds. New Box Tool We added the Box Tool for the Curve Editor and the Dopesheet Editor. The Box Tool will allow users to move and scale keyframes selection in time and in value. With this tool, you'll be able to easily speed up or slow down a portion of your animation.
