I tested this plugin out a little bit and loved the feature of drag&dropping widgets into your theme + this plugin feels very light and not that bulky, I like that.
Even creating your own widget works like a charm.
There is just one thing I like to ask.
I there any chance that you implement bootstrap, giving you the choice of organizing the column width via draging (percentage) or using the predefined bootstrap .row .spanX classes? (and maybe adding extra classes on each row/element)
My thoughts behind this are that ... people tend to be dump, and turning a well structured theme into a mess by not using the same percentages for each new row, resulting in:
33|66(|1 in that sense)
So I would like the idea of giving people limits.
