First time reviewer for a mathematical journal here.
I'm encountering a lot of little presentational flaws, such as typos and grammatical errors, but also LaTeX problems. It doesn't stop there, I also encounter (what I see as) problems in the structure of the text, for example, a rather important definition is "hidden away" in the text and referenced later, but it could be improved to be a standalone definition.
I don't know how far I should go in my review. Of course I'll point out all typos and grammar issues and require those to be fixed before publication. But can I ask people to improve their LaTeX typesetting? Can I ask them to restructure their text? Can I ask them to change the title in order to match the content better?
