Fantastic new Javascript debugging tool with IE 8 and its list of features hard to live without CoolWebDeveloper.com:

I have heard web developers complaining about earlier versions of IE for being
non compliant and also how hard it is to debug CSS and JavaScript in IE. Well
the good news is Microsoft has listened and with Internet Explorer 8 Microsoft
has launched Developer Tools (Developer Tools are available for a while now) and
that sets a new era in JavaScript and CSS debugging.
