A more intuitive "More comments" button

When a Task has a lot of comments, there is a button “More Comments” that only shows the alst 4 comments.
It is very helpful, but it causes misinformation, as it is a little bit inconspicuous (not very striking).
I would suggest de degraded to white in the forth comment, as well as a button shape in the line of the new “Task completed”.
Thank you for your support
