The new status feature (Missing, Late, etc.) is a huge improvement. However, it's missing at least one critical option: Complete. Without an option for "Complete," it's not clear whether a student has submitted the assignment or the teacher just hasn't marked its status yet.
Please add "Complete!"
Also, it would be great to customize other options, too. For instance, many teacher like to record that an assignment was turned in but not yet adequately completed. In this case, something like "Needs Revision" or "Incomplete" would be helpful.
