Feature summary (what you would like to be able to do and where):

When trying to categorize pages (wishes) in wish-categories using cat-a-lot, it doesn't actually categorize the pages.

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):

It would be useful to be able to categorize wishes by various topics also not (yet) covered by existing wish tags. For example, I'd like to several wishes to a new Category:Community Wishlist/Wishes/Maps which can then be browsed together (e.g. starting from one individual wish) and discovered from Category:Wikimaps and be linked/shared at relevant places in a bundle.

Benefits (why should this be implemented?):

See above. Relevant discussion1 and discussion2.

This allows users to find more wishes they're interested in or to find these more quickly. It also allows better sharing and bundled browsing as well as making it easier to find similar or related wishes. Additionally, people browsing the associated meta category can find these. Cat-a-lot is needed to categorize the wishes in practice, it can't really or at least won't be done by hand, especially not if the categories are supposed to be complete instead of overly incomplete/outdated.
