One thing that's been conspicuously missing from the web app for its entire existence is the ability to delete a student. This sounds like fundamental functionality, and in some sense it is, but it really just doesn't come up all that often. The few times it has, we've just directed users to delete students from the desktop app, either old or new, and that has gotten us over the hump. But we've finally worked this functionality in. And it's still being polished. It basically looks like this:

If you don't see it in your own web app, that's because either 1) you don't have a recent release and you'll see it in your next one, or 2) you're not authorized to delete students in your state. So not everyone will be able to see this button. And even those who do see it won't necessarily be able to just delete the student outright. For some users it will simply become a "delete request" which will then have to be reviewed by an admin and either approved or rejected.

Admins have always had access to this approval functionality like so:

And I think they also get emails when there are pending items to be reviewed.
