Hi Tom and Rhonda,
Whenever you make a change to the layout of the MediaShout control screen, you must then save it as a Workspace to be able to use it in the future. Under the Settings Tab, you should see the section labeled Workspaces. Here, you can click Save as New to save the Layout of the control screen to a new Workspace.
Please let me know if you need additional assistance with this.
Thanks and God Bless,
