How to create a unified starred folder?

I’d like a unified folder for my starred messages. There isn’t an automatically generated folder or tag. Ideally, there should be, but I’d like to ascertain whether a workaround exists (before I file a ticket at Bugzilla).

As this comment that quotes another user explains, chronologically:

  1. Select “Edit”

  2. Select “Find”

  3. Select “Search Messages”

  4. Select “Save as Search Folder.”

  5. For me, selecting anything except solely the individual “Inbox” and “Archive” folders - especially the “Starred” folders that GMail creates - caused duplicates to appear.
