## 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.

As of v2.0.0 uses [Userscripts Configurer][16] to provide configuration options. Currently, 3 options are available:

| Option    | Default          | Description |
| --------- | ---------------- | ----------- |
| Colored diffs | `true` | Color-code (red/green) changes in diff view |
| List type | `always-ordered` | Always prepend item number to items |
| View type | `list` | View to use for edit lists |

Example of the diff view:

![Diff view for the "duplicates list edited" timeline event with 1 target added and 0 removed][17]
