StagTools is a powerful plugin to extend functionality to your WordPress themes offering shortcodes, FontAwesome icons and useful widgets.
Love it - makes things real easy, and looks great.
Had issues with Shortcodes Ultimates on one site because of a ridiculously high number of queries coming from that plugin, and site performance was affected. Switched all sites using that plugin over to StagTools and I'm far happier for it. Buttons are super cool, the toggle (accordion) menus are very handy, and it's easy to use while also being lightweight.
Works as it says. Very cool.
