Yabdab has announced BootSnap (http://www.yabdab.com/bootsnap), a set of RapidWeaver stacks designed to simplify responsive web design for Mac-based web developers.

RapidWeaver is a theme based tool that allows novice to intermediate designers build modular sites with drag and drop widgets called stacks. You don’t need to know any HTML, CSS or JavaScript to build a web site.

BootSnap is a set of 15 stacks and a RapidWeaver theme. It’s available today for US$29.95 with future expansion packs scheduled for release in the coming months.
