From the developer:
Default App is a MacOS 8-only extension that lets you open documents matching certain file/creator types with the applications you specify, instead of the applications that created those documents. For instance, DefaultApp can be configured so that when you double-click a SimpleText document in the Finder, it gets opened in Style.
