A commit just a couple back in the series added these features.
Hunt overview commands and filters
----------------------------------
-• Implement a /hunt command for giving an overview of the entire hunt,
- (like the Turbot "home" view but available in any channel)
-
-• For "/hunt" display only unsolved puzzles by default, but also allow
- for "/hunt all" to display all puzzles
-
• On the Turbot home screen allow a dropdown for Unsolved/Solved/All
puzzles
