In-Line Document/Text Editing in ProofHQ

Please add a feature into ProofHQ where word documents can be edited in the ProofHQ system.

As it is now, if a copywriter uploaded a word doc, a reviewer can make comments by marking the static, uneditable version of the document, just as one would make a comment on a designed PDF or JPEG.

From a copyediting standpoint, it would be so helpful to have a feature that allows someone to edit the actual document--in the vein of "track changes" in microsoft word.
