We are happy to see your positive review of our editing work - thank you. Re the comments, we only usually comment if something is unclear, if we need the author to check, or if we feel it is necessary to explain why we have made a particular change.
We do not comment on every correction as it would take the editors hours to get through the documents we edit.
If there are any particular corrections in your paper that you'd like to discuss with us, just send us an email and we'll be happy to explain.
