• Leaderboard functionality when @WorkingPlusPlus leaderboard is sent (requires additional app permissions - see step 6 of the installation instructions), including a link to a full web-based leaderboard with a time-based token to protect your team's data
• Help message when @WorkingPlusPlus help is sent (requires the same additional app permissions as above)
• Contributors: a raft of new helper functions including isUser, isPlural and many more
• Contributors: additional tests to cover all previously added functionality (leaderboard functionality is not covered yet)

Changed

• Contributors: another set of significant structural re-organisations to set the app up for handling more 'direct commands' in future
