The IMPORTANT! tag is great, but it would be even better if there were notification sound options. I have a specific team chat room that I'm tasked with monitoring to assist other technicians in our firm. They post messages to that chat with the IMPORTANT! tag to notify us that they need our assistance. It would be nice to be able to set a specific sound that would go off when a high importance chat is posted.
