I made some default library images for those who like a clean, simple interface. The idea is to put the content in first place. Just in case anyone wants to use them.
I used the green from the default Emby theme, the icons are from the google material icon set, style set to rounded, to match the recent Emby style. (Although I do not like that everything needs to be round nowadays). Images are 16:9 / 1920x1080px png-files.
