It would be very helpful to be able to embed images or other media in the side panel of the new map tours. A lot of text flows with images and while you can put multiple images at the top of each item on the tour the reader has to scroll back to the top of that item and click through the images to see the image you reference in the text. It would be nice being able to embed between text in the side panel. Like many problems with these web based application editors, it could be most easily solved by allowing the user into some of the code for the HTML and CSS. But a GUI fix for this would also be helpful.
