Lightweight Grid Columns

Love this plugin works really well.

One really small point would be great if the button for columns showed up when editing a Toolset template, some kind of integration with Toolset.

Its not a massive thing as you learn the code you can just manually write it but would be a nice little time saving update if it was integrated! :)

Great plugin would be even better with Toolset support

Easily add desktop, tablet and mobile friendly columns to your content using an easy to use shortcode.
