Hey Nick, Flow isn’t a competitor to, say, Dreamweaver. Currently, Flow is best at creating layout and animations for components that you want to drop into your site – a button, a loading animation, etc. Flow excels at generating the layout / DOM + CSS, as well as the timelines associated with any animation.

It’s HTML export currently includes a driver that you can use to trigger an animation or have that animation respond to input from a mouse, or other events like scrolling.

That said… If there was a layout you wanted to quickly convert, Flow would be pretty good at giving you an initial structure of a page that you could then modify by adding custom elements like menus, buttons, content, etc.
