Wireframe Development Tools get Interactive

For the last year, I’ve been struggling to find a wireframe tool that was simple, added collaborative tools, and actually had interactive components that mimicked how HTML objects and elements actually worked. My search just ended with Hotgloo. From their site: HotGloo is a rich internet application designed to build functional online wireframes for a website or web projects. Create and share fully interactive online prototypes. Collaborate with colleagues and share the output with clients.
