Autotab just got a lot better! v1.8.0 release now allows you to dynamically update your tabbing order whenever you add or remove fields on a page with the new $.autotab.refresh() method. To show off this new feature, two new demos have been added, one using Angular, another using Knockout. Several bugs dealing with pasting has been fixed, and readonly fields are properly supported.

Looks like the jQuery Plugin Registry is going to die a painful death, so you won't find the latest version of Autotab there. NuGet and Bower packages are up to date, and I will try to get it listed on npm soon.
