Wow what a confusing mess Panels 3 and views is. I say that lovingly actually. Earl Miles is a genius and the combination of these two modules gives such incredible power. With great power comes great responsibility! The interface is awesome but trying to utilize the features is daunting to say the least. The documentation is lacking because the module is so new. To push Panels and views to the full extent of its power you ABSOLUTELY must understand how to use CONTEXTS and ARGUMENTS. I must say I have not grasped that yet. Once I do you can expect a Drupal for Dummies tutorial on it.
