// How to use:
// When you have a to-do with a deadline, just add the date in the following format [dd/mm/yy].
// The script will then colour-code the to-do-item as follows:
// today -> orange
// within the next 7 days -> green
// more than seven days -> grey
// overdue - > red

var today = new Date();

textnodes = document.evaluate( "//body//text()", document, null,
XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null);

for (var u = 0; u < textnodes.snapshotLength; u++) {
	 node = textnodes.snapshotItem(u);
	 s = node.data;
	
   var datum = s.match(/\[[\d]{2}\/[\d]{2}\/[\d]{2}\]/g);
   if(datum) {
       
       var datum1;
       var dateDisplayed;
       var future;
      	
       for (i=0;i<datum.length;i++) {
      		datum1 = datum[i].replace(/\[/g, "");
      		datum1 = datum1.replace(/\]/g, "");
      		datum1 = datum1.split(/\//g);
      		
      		dateDisplayed = new Date();
      		dateDisplayed.setYear( 20 + datum1[2]);
      		dateDisplayed.setMonth(datum1[1] - 1);
