Can someone help me to find out where js.category.single_page is used?
I cannot find it on my forum. Thanks to How can you find more context for a text? - #3 by gerhard I was able to find out that it was added here FEATURE: Simplify category creation, hide settings by awesomerobot · Pull Request #36998 · discourse/discourse · GitHub. But I cannot spot it in the screenshots or in the code.
