Watchlist sorter
Sorts your watchlist by namespace, and also adds spaces for readability. addOnloadHook(function { if (location.href.indexOf('Special:Watchlist') == -1) return; //Are we on a watchlist?  //days = document.getElementById('bodyContent').getElementsByTagName('ul');  days = document.evaluate( //Hell knows how it works - found in "Dive into Greasemonkey" "//ul[@class='special']", document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null); for (d = 0; d < days.snapshotLength; d++) { //For each day    day = days.snapshotItem(d);    newday = document.createElement('ul'); //This will replace the old listing    while ((diffs = day.getElementsByTagName('li')).length > 0) { //Are there any diffs left?      //Try to extract the namespace      As = diffs[0].getElementsByTagName('a');      if (As[0].innerHTML == 'diff')        pagename = As[2].innerHTML;      else        pagename = As[1].innerHTML;      if (pagename.indexOf(':') == -1)        namespace = 'Main';      else        namespace = pagename.split(':')[0]; //This will fail for articles which contain ":" in name      hdrs = newday.getElementsByTagName('h5'); //Get the list of namespace headers      hdr = null;      for (j=0; j<hdrs.length; j++) //Find the header        if (hdrs[j].innerHTML==namespace) {          hdr = hdrs[j]; break;        }      if (hdr==null) { //Not found?
