Group channels
Your Slack Sidebar may look overwhelming and messy after joining a lot of channels. We highly recommend you create sections (or groups) in your Slack Sidebar to organize channels joined.
- Click on the 3 dots next to Channels
- Click "Edit sidebar"
- Select the channels you'd to group together
- Click "Move to..." and select either "Starred" or "Move to new section".
