Preservation of original key frames after baking actions on animated objects

It would nice if blender could intelligently recall original key frames after baking actions in the graph editor, dope sheet and timeline, so that it is possible to recall the original keyframes. Add the possibility of selecting baked keyframes excluding original keyframes making it possible to delete baked keyframes.

Note it would also be nice of bake curve in the graph editor operate like the action operator right now the bake curve is only freezing the curve and deleting key from the dope sheet and time line there by losing feed back of the key frame data.

thanks.
