* Prettify history titles. They're now Special:AbuseFilter/history/<filterid>
* Prettify history *pages*. They now truncate the filters at a few hundred chars, and have links to open the individual history items in the editor, with a big boilerplate at the top and the bottom in case people forget.
* Fix up the log a bit. <li> elements in the 'details' view were invalid XHTML, and very annoying...
* Fix up selecting deleted / disabled filters on Special:AbuseFilter. Instead of weird links, it now has a proper form.
* Fix log entries so they can have wikitext, and add a link to the relevant abuse filter for detailed log entries.
* Allow matching on the changes made in an edit (added/removed lines, etc)
* Improve display of variables in details view - standardise the table size, add white-space: pre, font-family: monospace.
* Improve modifiers: add htmlencode/htmldecode/urlencode/urldecode.
* Add 'abuse filter tools', currently consisting of a testing ground for the modifiers. In future, may include facilities for testing filters against user contributions, recent changes, or other sources.
