I don't see the usefulness of this type of delete. It sounds like the only way to make the
web application useful again would be to change the manifest.

I was thinking "Delete" would actually eliminate the application cache you're viewing. The
use case goal being you can use the delete button, and then refresh the page to re-download
the resources _even if the manifest didn't change_!! Is it enough to just "obsolete" the current
application cache? Considerations would include disabling the delete button when its
not appropriate.

I think this is a great idea. The difference between this an the "Delete" semantics I describe
above would be that here nothing would be re-downloaded if the manifest has not changed.
