Models are able to export print layouts from the current project. One use case for this is allowing users to create an in-project model which exports a particular set of layouts from the project to certain folders, so that they can easily re-export the current project in a single operation instead of having to manually open multiple layouts and export one-by-one.
Additionally, with the new capabilities to have expression based output files inside models, you can automatically export the layouts to a folder with the current date tag and include this in the exported file names!
