**Task:** Include a bar with the title "RevisionSlider" on top of the diff view page. Only load and show the revisionSlider once this element has been clicked. Hide the RevisionSlider if the bar has been clicked again. For the design suggestion, see the comments below.
**Motivation**: When testing the revisionSlider as a beta feature, we received some feedback from testers who did not want to see the revisionSlider at all times they open a diff view, since it takes up some space of the page and may take a while to load.
The revisionSlider is a feature that adds a visualization of all revisions to the compare screen. Revisions are represented as bars on a line and can be selected using two pointers. The revisionSlider was originally prototyped by the WMF Community Tech team and then handed over to the WMDE TCB team, as it is a solution to fulfill a wish of the German Community Wishlist:
