Threaded collaboration has transformed how our team tracks tickets and monitors automation updates
One suggestion I would make for improving Slack Business - Enterprise is the support of multimedia such as images and videos that we can easily share through Slack. That would be great. Additionally, another thing is AI integration; if Slack has some AI capabilities to get insights about conversations or summarization, that would be a great feature. If Slack has an AI feature that can summarize a particular Slack thread and provide a summary of that, that would be a great feature for us. I would rate it a ten if it comes with some AI features, particularly using generative AI to produce summarization and other kinds of insights from communication in a more secure, data-secure way.
