Folder structure would make organizing questions easier.
In the context of higher ed, we are using PE for things like test review. It would therefore make sense to have a folder structure on the My Polls screen, such that I could place one set of polls (really poll questions) in a folder called "Midterm Review" and another set in a folder called "Final Exam Review."

You're in luck. Log back in today and you'll see some Grouping buttons at the top of the polls list. Try it out. It's not a full hierarchical folder structure but it will give you one-level deep where you can group polls together and even collapse/expand the groups you create.
Look for further enhancements to this functionality as well over the coming weeks.
