Hi John
If your existing Map Tour has a subtitle in its header, that subtitle is not displayed in the Side Panel layout's header. By design, the Side Panel header only shows the title of the tour, and doesn't show a subtitle in the header. We do this to maximize the space available on screen for your places, and also because you can use the optional cover page in the Side Panel layout to present your readers with subtitle info, like in this example Seven Wonders: Natural World
To present your Side Panel readers with a subtitle, edit the caption of the first point in your tour so it uses your desired subtitle text (or add a new first point into your tour if you don't want to change the caption of your current first point). Then in the Organize dialog, make sure the option to use the first point as a cover page is checked (it will already be checked if your existing Three Panel or Integrated tour uses the option to use the first point as an introduction).
Tip: Normally you'd want the title that appears on your cover page above the subtitle to be the same title that appears in your header, like in the example above, so you can edit the name of your first point, which defines the title on the cover page, to be the same as your tour's title. But if you like you can also take advantage of the ability to have the title that appears on your cover page be different than the title in your header, see for example Kilkieran Bay Marine Life .
