be able to change the background of a layout from a list of choices, images, videos, html package as these are the ones that have currently a library implemented. Webpage url and embedded content could be also some potential candidates
Movement and animations are very eye catching on digital signage screens. Right now you have to create a top region show as background and the content regions to show the layout content. You can use a template but anyway, you are mixing “layout” and content on the timeline.
I found that there is a current feature just for videos marked as duplicated, but I can’t figure the original request to add my comments as posible improvements over the original.
