One of the most powerful Sibelius plugins you will find. It has been a publisher secret for the last two years and is finally available to the public. If you ever need the layout from a score, you could spend hours manually making formatting marks, or you could simply import the layout using this plugin.
This plugin allows you to Import or Export Layouts from one score to another or to a dedicated Layout File Type (which are saved as .txt files). Using layout files is incredibly powerful since not only does it let you email layout files to other engravers, but you can export layout files at any given time in a score and import it later if you need to return to it.
If you deal with editing previously released engravings or are just a thorough engraver, this is an essential plugin for any Sibelius professional.
