## About

The native post timeline displays "duplicate lists edited" event as a barely readable blob of links with excessive verbosity ("duplicate list changed from [list of links] to [list of links]"). This userscript *diffs* the changes and displays them as easy to visually parse lists of items.

As of v1.2.0, also fixes duplicate list edit entries on /revisions pages.
