Star-Rating and Tree-View on K2

Hi everybody,

I just bought Kommento to replace the inbuilt comments of K2. Kommento is much niver and Stackideas has a great reputition. ;-)

However, there are two Issues that I don´t understand right now.

1. Star-Ratings
It seems like the Star-Ratings are double. When I deactivate the rating in K2, I can´t see any rating on the category-view, which I guess is important for the users. When I activate bouth ratings, they are not "connected", I can rate an article with 1 star in K2 and with 5 stars in Kommento.
In addition to that, there seems to be no way to rate an article without commenting it.

I think the best is just to disable the rating in Kommento, but I wonder if you have a better solution.

2. Tree-View
I like to have "nested comments", but while I have put all options to "on", there is no way to "answer to a comment". All comments are placed under the other comments, nothing nested.
Is this a bug or did I miss any setting?

All the best, Julian!
