About this ticket
This is the umbrella ticket for tasks you can do around the RevisionSlider. If you liked the work on it, the Season of RevisionSlider might be something for you!
@Addshore can mentor you here in Capetown and @WMDE-Fisch through IRC.
The RevisionSlider is a MediaWiki extension, developed bei Wikimedia Deutschland’s Technical Wishes team. It adds a slider to the diff page that allows to easily navigate through revisions. The feature got developed in 2016/2017, and is a default feature on all wikis since May 2017. (Extension Manual: https://www.mediawiki.org/wiki/Extension:RevisionSlider)
