SUMMARY
***
Add button to filter on no stars
***
The UI is unclear how you can filter all photos with no stars. There are sepate buttons to select photos with no color label or no acceptance flag. There is no button to select photos with no stars. You have to do it pretty complicated using the 'None' button of the colour label buttons plus a change in the rating filter options (equal to or less than). Even for multi-year users, like myself, this is not very straight forward, especially when working with software like darktable that do have a separate filter button for photos with no stars.
So, can you please add button to select no stars (left to the already existing star buttons)?

STEPS TO REPRODUCE
1. Select an album
2. apply filter
3.

In the dropdown tool button next to the star rating filter you have the last option “Exclude Items Without Rating”. That's exactly what you're looking for.

Ok, the post from Pixls.us makes it clearer what is desired.

Yep, the functionality is there, but the UI is not clear how you can use it. There are dedicated buttons for 'No colour label' and 'No flag', so users will also expects a button for 'No stars'.
