Move the users list to the left sidebar
By default, the Users list is displayed on the right sidebar located at the right of the Zulip window. However, on devices with narrow screen widths of under 1165 pixels, the right sidebar is hidden to save space. If you would like to see the Users list on your mobile device, you can choose to move it to the left side of the screen under the Streams section in the left sidebar.
You can easily change the location of the Users list by following a few steps.
