It would be valuable to be able to filter out or highlight edits that have already been "rolled back" or "undone". This task is about adding a "Reverted" filter to the Tagged Edits interface in #mediawiki-recent-changes
{F31616248 size=full, alt=Recent Changes UI}
We will want to identify the edit that is being reverted and tag it with a "reverted" tag.
We'll need to detect when a revision is being rolled back / undone, and then apply a tag to the revision that it is rolling back. This involves defining a tag and implementing a hook which can apply that tag in certain conditions. Potentially we will also do some work on {T152434}.
## Skills required
You'll need to know how to code with PHP, with a flexible range in how much knowledge you have before this project starts. There are varying levels of work that can be done to implement this project.
