You must unlock the Just Control Configuration window and stop the channel(s) to be able to make any changes.
Changing the name of a Layer will change the name of the Layer in the user interface. Use less than 8 characters for just:play and less than 4 characters for the just:live user interface, otherwise the name will be shortened.
Stop the desired Channel by deactivating the checkbox in front of it. Stopping a Channel will also stop the Just Out engine and therefore the final output.
Select the Channel in the Devices & Channels list.
Click on the Layers & Engines tab.
Click on a Layer name.
Enter a new name and press the enter key afterwards.
Activate the checkbox in front of the Channel to start it again and to take over the changes you made.
Close the configuration window and drag the Channel from the Connections tab to the Multi-viewer area.
