When you use the sample in the motion clip for some part of the body, you can edit the key frames. But it would be great to be able to see the translation and rotation keys on the XYZ axes for each key frame in different time lines. Being able to clean up motion capture files faster. Or a smother option that helps remove shakes from files.

  Would be like this:

Right hand:

                       X rotation:

                       Y rotation:

                       Z rotation:

                

                      X translation:

                      Y translation:

                      Z Translation:

It is not a definitive solution, but it would help to delete key frames on axes that that shouldn't have keys
