I work with editors and proofreaders, but I make the final decision about how a document will be edited. At times, I do not agree with some of the editors’ comments in a document. With Word 2003, I could delete a comment I did not want the reader to follow without the original comment’s or the deletion’s being visible. The editor’s comment would just disappear, and I did not worry that the reader would be confused. Is there a way to completely omit another author’s comment without a trace with LibreOffice? When I delete, the undesirable comment seems to still be visible but with an X through it.
It might no be exactly what you desire but you can switch on/off the visibility of comments in general.
Menu: View > Comments (toggle switch)
Go to one of his comments and open the drop-down list from the triangle in the comment. Find the item “Delete all comments by user name”.
The cross is produced, if you have change tracking enabled. So before you delete a comment, turn change tracking off. It is in menu Edit > Changes > Record.
