Images in the Sidecar default to 'Fill (crop)'. The majority of the time this is not the best option for images, and for casual StoryMaps users, this is not intuitive, and may lead to frustration, or abandoning using a StoryMap all together. It is also time consuming to have to edit every single image in a Sidecar.
I would like to propose that the default either be set to 'Fit (do not crop), or that the StoryMap creator is given the option to choose the default, perhaps when adding a new Sidecar.
