Release 2.8.0 and above.
In the Synap Editor 2.8.0 release, the editor script files were made more lightweight by separating import features and shape-related features into external modules.
To continue using the shape-related features as before, you must additionally include the file below.
To import documents containing shapes or to use the features of the shapeEditor plugin, include the SEShapeManager module located under the editor package's externals folder.
