Problem: Templates are different on each wiki and language edition. When you edit in multiple languages or multiple wikis, you have to re-learn the syntax for the templates. For example, in English Wikisource, writting "wikisource" hyphenated on two pages would be {{hws|wiki|wikisouce}}, while in the French Wikisource, it would be {{tiret|wiki|source}}. This makes contribution in multiple languages really difficult.
Proposed solution: Have a global library of templates and Lua modules, where it is possible to access the templates from any wiki.
Who would benefit: Anyone contributing in multiple languages or on multiple wikis
