NewDocumentPlugIn adds a "New document" contextual menu to the Finder. You can thus create easily new documents without opening the associated application. It works with Mac OS 10.4 to 10.5 (untested on Snow Leopard).
When creating a new document, the document name is highlighted, in order to customize the name without superfluous keystroke (ensure that GUI Scripting is enabled for this).
You can easily add your own templates : just drop an empty file of the wanted type in the "Templates" folder of the plugin.
The plugin is localized in English and French. You can add localizations for the contextual menu labels and for the document names if wanted.
NewDocumentPlugIn uses CoreFoundation and AppleScript.
