RapidWeaver theme designer Seydoggy (http://www.seydesign.com) has released Havnit Ultimate, a new theme to date that introduces “smart navigation,” “smart layout” and an advanced built-in slide show. It also embraces technologies like CSS3 and HTML5.

“Theme developers previously had to account for end users’ choice to opt into or out of some of RapidWeaver’s built in features by creating numerous and often insignificant theme options,” says SeyDoggy lead developer Adam Merrifield. “Havnit’s new smart layout is able to automatically detect and account for the presence of a footer, a breadcrumb, enabled navigation, and even ExtraContent.”

Following the trail blazed by a few other RapidWeaver theme developers, SeyDoggy is adopting future forward methods and employing the new HTML5 and CSS3 working drafts, he adds. Because of this, SeyDoggy is fast tracking on their upcoming modern browsers support policy by a few months. Havnit officially supports IE8+, Safari 4+, Firefox 3.5+, Opera 10.5+, Chrome 5+. Havnit is said to work with IE6 and IE7 but the experience may be somewhat hindered by speed.

Havnit Ultimate requires Mac OS X 10.4.11 or higher and RapidWeaver 3.6.7 or RapidWeaver 4.x. It’s available for $20.49 CAD at SeyDoggy’s online RapidWeaver theme store.
