When setting up a new job, the Ribbon Bar with action items goes out of view when you scroll down. It would be nice if the Ribbon Bar stayed put and only the content section scrolled.
This way, when I discover I need a new mapping for example, I can create one without scrolling up. For columns, in particular, I have to scroll all the way do see if my field is there. If it's not, I scroll all the way up to click the button, and all the way down again, to select the new field.
