#1 - After you click the '+' sign to select an Object, it's not clear that you need to click on the object name again to get the fields to show up in the field selection box.
#2 - I find that I am almost always in the process of building a rule when I realize I need to add an object/field to make it work. It would be IDEAL if we could either 1) Open the Data Load Configuration page in a new tab so I can keep my rule page open or 2) Have a button to take me back to my rule or at lease back into the Rule Engine
