It would be useful to add an indication or segregate the comments added by the version of the document they were added to. For example these are the comments added to version 0.4 and these comments were added to version 0.5 since the comments are carried forward for all newer versions of the document. In some cases, comments against an older version no longer are meaningful to the newer version and it would be useful to tell which comments still are valid to the specific document version
Thanks for this idea. This could indeed be useful when we speak about normal comment (as the ones in the right pane of the tool).
