The steps involved in designing the rubric walk you through the process in a way that forces one to connect the assigning of the grade and the learning objectives of the product. I will use this again.
Returning to incomplete rubrics requires one to move through the steps linearly from the beginning (e.g. you can't jump straight to step 5 even if 1-4 are already completed). I don't see a way to increase the weight of a category or to modify the points for different categories. Printing options are limited.
