Maybe it's just me, but when I want to edit and revise an old comment/rating, I always have a bit of trouble finding my first comment/rating - endless scrolling. Maybe you could make it so that my own comment is always the top one - for me?
If I then edit the comment/rating, it doesn't move to the top. I think that's a shame, because it's usually a new rating - different from the first one, otherwise I wouldn't have had to edit it. And so perhaps it could also be interesting for other users?

LG ond e schöne Sonntig,
Kathrin
