I am working on documents that are published online, with video and sound features. If a file is packaged and sent to other members of a team, upon opening the Indesign file, you are required to relink all media in the Links folder. However, some features are then lost, like the Poster frame settings for Video files (set in the Media panel).
It would also be useful to be able to have the option to have sound on or off when publishing online, without having to do this in another application.
