Key Features

   • Minimum vote threshold before allowing submissions
   • Custom completion messages
   • Optimized statement ordering (least voted first)

2. Anonymous Participant Tracking:

   • Persist participant progress across sessions

Implementation Details

• Feature flag: advancedOptionsEnabled in CommunityModel
• New nullable columns in Poll table
• Optimized statement sorting algorithm
