Hello,
I'm using Gridbox for a magazine website and, despite some needs that I believe and hope you will consider someday, liking very much. Gridbox is far away the best resource I know, including comparisons with the most used similar for Wordpress.
One suggestion: I believe is easy and would be very useful include a away to show a Google Adsense slot in a post plugin. For example: a 3 column and total of 9. Would be possible to choose for 1 or 2 of positions to show an ad from there. They offer an "in-feed" ad that fits the layout, just need to inform the ad-client (ca-pub-xxx).
Would be awesome!
Just think about it.
Thank you
