Access from the application menu: File -> Export. Or press CTRL/CMD + E.
These are the currently cupported export options:
Will create a text file from all the selected shows.
Will create a PDF for each of the selected shows. Here you can tweak a lot of settings, like to only export lyrics, only slides, or both.
This will export a .project file, containing the current project list and all of the shows contents. This can be imported by FreeShow on another device. Media files have to be transported manually right now.
