This new version of the classic #MediaWiki theme improved responsiveness, dark mode support, a collapsible sidebar, and more.

Fourth place goes to Timeless

Timeless features a left sidebar for navigation and a right sidebar with links to tools.

It comes bundled with #MediaWiki, so can be enabled with a single line of configuration. Naturally, it is also available on pro.wiki as the default theme for new wikis.
