If you are using the newer version, check out the documentation for Views Natural Sort 2.0.Recently, due to an issue I got in my issue queue on Drupal.org, I realized that there may be a bit of confusion about how to use Views Natural Sort. The following is some information on how it works and a quick guide on how to use it.
I've been plagued by the fact that at work I do my development on a remote system. This generally isn't a problem except on the rare occasion I want to use a debugger, since I'm a Vim user. However, when that time comes (and it always does), I have to sit there and wait while eclipse "builds" my project. Nothing irritates me more than "Hurry up and wait". Since I started working with Drupal, I've found this to be a very common theme. It's far from the speed that I got out of Zend Framework, or other MVC based frameworks, but it does so much for you.
