Sure, we can make edits if you don't like how the text is written.
Keep in mind, it is better to leave any exact notes for the author, cause, in this case, the author will better understand what he or she should edit for increasing the quality of the text.
As for notes for the author, you can write about all points that are not appropriate in text like semantic or grammatical mistakes, insufficient or one-sided disclosure of the topic, the omission of important information, or logical inconsistencies.
The exact definition of the edit points will help authors finish the material faster and make the publication better.
