I would like to add to this suggestion to have it monitor folders (and subfolders) for new items for random mode. It is a big pain to add a few new animations, and then wait for the UI to render all the thumbnails for ALL of your dreams before you can select everything and add it to the random backgrounds.
I have forwarded your report to the Stardock support team for their review and recommendations.
Please keep an eye on this thread for any updates.
We really do appreciate your feedback, thanks.
