After getting the hang of the system, LoudCloud makes grading several assignments in a sitting quite simple. Improvements have been made (like having the due date and submission date / time easily viewed for each submission) that make it even easier. Review collected by and hosted on G2.com.

It's often difficult to easily find out what students see vs. what the instructor sees. I also have to manually go in and display student grades on the Progress tab for each class and I wish that was the default. On the student side, some students have continued difficulty uploading assignments (it's not a super common occurrence, but it's not rare) so there must be something not intuitive about that process.
