I don't mean to be blunt, but the new developer toolbar in IE11 is absolute rubbish.
The ruler and colour picker have gone completely which I don't understand, even in responsive design you need to know the size of images and elements. The colour picker was also extremely useful. What is the thinking behind this decision?
It's slow, cumbersome, requires a significantly larger proportion of the screen, and it's even lost the resources dropdown to view imported script and css files for example.
I'm sure the profiler and UI responsiveness tools are very good, but not something I'd miss to be honest.
Please can we have an update to make it usable again?
