Template Shelf is a new plugin for Movable Type 4.0 that adds a sidebar widget to the template editing screen. It provides a list of all the templates on your blog and allows you to easily filter and browse your templates. It's an incredible time saver as it saves you all the clicks of going back and forth between the template listing screen (and the various different filter types!) and template editing screen.
One of the best features Template Shelf provides is template editing within a dialog box which is really great way to make changes to template modules and other includes as the dialog box opens directly on the page!
I thought I should let the features speak for themselves. The screencast below highlights some of the features Template Shelf offers and how easy it is to use them:
