The RevisionSlider would be much more useful if you could filter, which changes are displayed: I am missing a filter by author: If you see some changes on a page which are not neutral for example. Then it would be useful to check which other changes were done by this author (and no: the history of the edits of this author helps only if the edits were not done over a long time frame).

Filter by Author missing
I'm afraid this request is a bit out of the scope of this project. RevisionSlider currently does not provide any filter. Instead, we are currently investigating possibilities to highlight edits, e.g. edits by a specific user. At the same time other teams are working on RecentChanges and Watchlist filters. Please check this out: Edit Review Improvements/New filters for edit review.
