Too many Polypads is the kind of problem we like to hear about! The "Done" and "To Do" feature is a good idea and I'll add it to our ongoing list of teacher suggested features. I don't think we'll get that out as an update anytime in the short-term. A few suggestions in the meantime:
- Student can make Folders for their saved Polypads. The can call one folder "Done" and drag the ones they've finished into that folder.
- If you're done with one, you can "Unassign" the Polypad to your classes in our teacher dashboard and then it won't show up in their assignments anymore.
- You can give them time one day to delete ones (or put into a different folder) the ones they no longer need.
Hope this helps somewhat!
