This link shows 2 problems with the column layout where the content is cut off. I’d like it if 1. the boxes resized vertically, or 2. they had a minimum width, or 3. the content appeared in a popup on mouseover.

I would also like it if there were (an option for?) a bit more of a preview of the content of each widget.
This link shows how the column divider overlaps the row options popup.
