Currently (5.0.4) in the "Manage Changes" list of "Compare Document" of Calc we do have the following Columns: Action, Position, Author, Date, Comment. In the Comment fields we find (when, for example the value of the cell is changed) something like this: "Cell (Position) changed from (Position.Value.in.File.1) to (Position.Value.in.File.2)" While the information is useful I think is not clear enough, specially when data entered in the row is too large (a large formula or text). In my opinion, the Columns Libreoffice should have are: Action, Position, Author, Date, Value 1, Value 2, Comment. In "Value 1" and "Value 2" should appear what is now in the comment, and, because of that, the comment shouldn't have any values in it.
Valid enhancement, setting to new.
