I tried that during previous experimenting. Just tried again to make sure, but it is still not working. Here is the entire plugboard:
Code:
kepub:KOBOTOUCHEXTENDED = ([{#pg_ct:|<div>Pages: |; }{#wd_ct:|Words: |; }{pubdate:|Published: |</div>}{#last_read:|<div>Last Read: |</div>}{#gr1:rating_to_stars(1)|<div>Rating: | }{#gr1:| |</div><hr/>}{comments}] -> comments)
I added the numerical value from the same column so you can see the rating of 3.88 in the image. Only 3 stars show, where I assume it should be 3.5 stars.
