Hello,
I suggest that sorting by priority should appear in the "sort list" in the Kanban module.

I have tested that it is possible to achieve with a filter. However, not having it in the main sort list has two drawbacks:
- I guess it is a common need, so if it is not a standard mode, it means that many users will have to create their own filter
- with another filter, we may need to change rapidly the sorting mode (from responsible to priority) which is not convenient with the filter tool.
- I think this should be the default sorting mode

Best regards,
