It would be great to see it update real-real-time during the drag aswell.

As you can notice on the inspector on the right, the actual value used by the Animation is only updated when the mouse is released. This is likely done to performance reasons as to not overwhelm the editor with inspector updates.

It's possible we can find a middleground (e.g. updating the value 5 times per second at most), but it might introduce stuttering while you're dragging a keyframe in the animation.
