In some scenarios the bandwidth is limited and preloading all the items in the menu takes a lot of time, for example when using a cellular connection.
This might take more time to load the UI and eat up a lot of bandwidth (depending on the size of the videos). The preview might even not be needed at all for some users (as in my case).
With an option 'video_preload: false' a static icon can be displayed instead of the preview image and speed up the page loading. This is not a breaking change as nothing changes if the option is not present in the config.
