" Now, there is a new sort by: 'Name' visible" Where do we look for this please?

Can you give me a screenshot or a bit more details?

Hi Daniel, I figured it out. Thanks!

For those in the future who are curious, this new "name" option will appear in the widget under the "Filter" section, as a choice in the "Show" field, (which might perhaps? be better named the "Sort" field.)
