Blog talk:Adnoam/Restructuring Qualities and their categories/@comment-25219384-20180314221114
From Fallen London Wiki (Staging)
Update: I've made step #1 in my list above easier:
Go to any page in Category:Qualities without Category. You'll see a link to create the missing category, including the code to put into it ({{|Quality uses}}).
When you go back to the quality page (you might need to force a refresh from the Edit drop-down menu), it will either show the collapsed list of categorized pages, or (if the category is empty) tell that no pages use this quality.
