Thanks to John Long, Rails now supports multiple view paths for each controller. For 90% of the apps, this probably won’t make a huge difference. But, for those of you wanting to productize various open source apps, you can now do this:

What you’ve done is created a minimal rails plugin that inserts a ‘views’ directory in the plugin to the beginning of the #view_paths array. Now, copy a view from the rails app into the plugin’s ‘views’ directory, make a noticeable change, and start your app. You’ll notice that it picked your plugin’s view over the application’s view.
