Currently, when a new category is created, even if it is linked to Wikidata and other language categories, there is no easy way to generate a list of articles that exist on a given wiki that should be populated with it. And even when someone has a list of such articles, they have to manually tag them. I'd like to see a tool that generates such lists, and allows populating categories with as much ease as Commons:Help:Gadget-Cat-a-lot.

Existing tools that solve (part) of this proposal:
- @Magnus's CatScan CrossCats (does not return results within ~5 mins for Category:Polish skydivers)
- @Mormegil's Category Completer (only one level deep, integrates with hotcat)
- LUA as used on cawiki / ruwiki / etc. to autopopulate categories
