I'd like to be able to download a list of students who submitted an assignment. This would make it easier for me to set up marking allocations among different markers, and I'm sure it would be useful in other situations as well.
If assignments are submitted via the external TurnItIn LTI API, you can export an Excel file with a list of students who submitted (one per row). However, this function doesn't seem to exist in Speedgrader. You can get a list of marks from the Gradebook, but until the assignment is marked, there doesn't seem to be a good way to figure out who has actually submitted. It would be nice to have an option to just download a list of submitters, or a full spreadsheet of students with a column that just indicates whether each one submitted something or not.
