Hello, On the right side of the screen (sorry forgot the name of the field that shows all the "tag 2" fields), it is very easy to change the star ratings by just clicking on location the stars. However, it seems currently impossible to change the star rating to 0 inside the rating field (you need to click on Edit and change the values in the box that pops up). For a feature suggestion, it would be nice if clicking again on 1 star makes the star rating disappear again (so it would become 0 stars). This is the way it works in Tag&Rename. Hope this makes sense. Thanks!
Setting to zero stars is also possible using the keyboard with the cursor left key. I have now fixed this so that clicking again on 1 star will set it to 0 stars. You can test it using kid3-git20230722 from https://sourceforge.net/projects/kid3/files/kid3/development/.
Fixed in version 3.9.5.
