Hello,
I have developed a gadget tool named StructuredCategories that allows to generate a structured description for a Wikimedia Category (e.g. Categories in Wikipedia, Wikinews, Wikispecies and other Wikimedia projects) based on the most common Wikidata statements of its direct members. The JavaScript Source Code is available at https://www.wikidata.org/wiki/User:Csisc/StructuredCategories.js. I ask if this tool can be added to Preferences in Wikimedia Projects.
