As Bootstrap is the industry standard for website and app grids, a very powerfull addition for RadEditor would be a Bootstrap grid builder like this one:

How cool would that be, building your Bootstrap parts in the Editor itself. Did anyone try this? Any hints on how one could build this functionality.

Let me know if we could collaborate to get something like this.

Thanks,
