Ages ago I observed that the ‘Add New Document’ link in a summary toolbar takes you to an ‘Upload’ page, rather than creating a new document based on that template, and suggested doing something about that. That was a bit of a hack, though, so now I’ve written a web part to allow you to display ‘Add new…’ links and if you click on them, it opens up a new document based on that content type’s template. I’ve called it the ‘Create New Document Web Part’
