* Display result below the field, rather than at the top of the page.
* Clear the result when the field is changed, not after some arbitrary time period.
* 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...
* Consolidate details on the last edit.
* Allow specification of a warning message to display instead of the standard warning (was already implemented in code, but there was no UI for it.
* 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.
* Reimplement tools, starting with a spiffy AJAX expression tester. Didn't bother implementing as non-AJAX, as it's just an extra.
* Change exchange protocol between native parser and PHP app. Resulted in 2-3-fold performance boost.
* Fix minor bug from last night.
* Introduce a syntax check on-save.
* Introduce filter history (requires DB schema change).
* Deprecate now non-working /tools interface (will come back).
* 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.
* Disallow more than 100 condition-checks per action.
* Disallow filters which are misbehaving (more than 5 matches, constituting more than 5% of recent actions)
* Display statistics for all filters (percentage of times the condition limit is reached, and percentage of times some filter is matched), and individual filters (percentage of times it's matched).
