 * Patrol flags/links will sometimes show up where patrolling is not enabled.
 * This was a bug in the API that generated patrol tokens too often.
 * Fixed in http://svn.wikimedia.org/viewvc/mediawiki?view=rev&revision=49000
 * Checkbox for batch patrolling
 * Parse comments
 * Add (talk|contribs|block) links, click their name, lazy
 * Localize error messages or focus on the log message 'logaction' (wrong tense, but it works fine).
