It seems obvious to me that the EMET GUI can be improved. The most obvious improvement would be the ability to add applications to the Application Configuration view from the Running Processes view.
At this stage the DEP column really doesn't need to be in the default view, while adding a Path column would be very useful.
Also, the notifier to give me a pop-up when I launch an executable which isn't in its application list. I would then be offered the choice between configuring it or having the notifier ignore it.
