Course Presentation within Interactive Book

I'm interested if others use Course Presentation within Interactive Books for similar reasons to myself - which is essentially to lay things out horizontally beside each other e.g. two columns of bulleted lists,  text beside graphic, a row of dialogue cards.  I often find myself using a single-slide course presentation for such uses. (I turn off surface Mode so I don't get the "slide 1/1" displaying)

Does anybody else do this for the same reason- or are there other ways of of achieving these kinds of layout in Interactive Books?
