I like the new UI, it's very functional. The only thing I dislike (and already disliked about the original) is the parameter selection.
I'd prefer to be able to edit parameters without having to click "Okay". For example, some GUI where the parameter is followed by a combo box in a grid layout, clicking on the combo box allows selection of the parameter.
Add to that, a new parameter type could be a range value, for example specify a parameter "Patrol Length" that displays a slider instead of a combo box and allows you to set any value in a certain range instead of only 1 hour, 2 hours, etc.
I also agree that the buttons for side selection are a bit too large, and would probably be better off as tabs on top of the roles list.
