I think the classifier could also include some meta-data about the template itself. For example, aside from "type", a simple description, e.g. "This template displays the best fighters in Mortal Kombat!". This could also be stored in the database, and then presented in Special:Templates.

That could sometimes eliminate the need to preview the template. In cases where a template description isn't enough, a tool like hovercards   could suffice and wouldn't unnecessarily waste bandwidth.

Hmm, maybe I'll add that to my javascript gadget...
