If you insert a column break, the next column will take on the layout characteristics of the previous column setup, including number, gutter, width and, most importantly of all, the before and after settings.
I haven't had much luck using the after settings, everything pretty much just drools down the page, but for the before settings...
Well, say you have a column which has a 'before' setting of two inches, leaving a nice empty avante garde white spaceabove it. If that column or series of columns extends down the page full of
boring incredibly interesting text and whatnot, and it stretches down to a half inch of the bottom of page, adding a column break will push the starting of the next column to the next page.
Inserting a layout break will do the same thing. The following column will take on the characteristics of the preceding column until you change it in the layout inspector.
