Thanks for the idea.
We've seen similar functionality created as an extension, for example, that adds a "Save & Comment" feature. However, the extension does not use the standard commenting field.
As a follow-up to the community, who would typically be expected or able to create or adjust a comment? Would anyone be able to change a Comment or certain people?
Does it matter if these notes are in the current Comment field? Would a separate, possibly new field, be just as useful?
Finally, would a change to a comment count as a change to the item's version? For example, if a user could change the comment on item version 2.0, would this remain the same item at version 2.0, or might this count as a change to the item?
