Hi Tom,
in a previous post you recommended a plug-in (Grid columns) to make responsive columns. You were also saying that you had your own add-on in the making, when are looking to release it? I am asking for the following reasons: 1. Grid columns appears to be only compatible with WP 3.7.X and 2. you were saying that it also needed some edit in the CSS and I have no clue how to do this! where would this need to be done? (can you send a path?). Many thanks, Anne
