Currently, using just 1.11.2 core functions and the ParserFunctions extension, working on templates and other cleanup-related things is really somewhat like working with one hand tied behind your back. There's some things that can only be done in rather clumsy ways, such as cleanly implementing through a series of parameters or "watch"ing all pages in a category (such as Candidate for Deletion), and some things that can't be done at all, such as testing in a template to see if a page is a member of a given category, or testing if a page has a particular string in its name.

So, to improve this greatly, could the following extensions be installed?

All are rated as being 1.11-compatible, so there should be no issues with conflicts.
