Since there is going to be an update on the List input on Vmix 18, I think it's the right time to plug 2 of my older request once more:

Add multiple display types for photo and list inputs. Give us the option to show it with big, medium, small thumbnails or just as a text.

And please make it possible to add pictures to the list and to set the display time of each images individually. This way we could have playlists/slideshows consisting of videos and images.
