mod_csi_muc_priorities: Reduce importance of group chat messages This helps if you are in more noisy public channels than small private group chats. The short term plan is to give users the ability to set MUC JIDs as either high or low priority and use that. Long term it would be great to be able to automatically classify MUCs as public channels vs private group chats.
