Automatically convert a 2-column layout into a 3-column layout, or a 3-column layout into a 4-column layout (or vice versa) without manually figuring out the right width and position of all the elements in each column. Background: some templates have a 2- or 3 column layout, but if I need a different number of columns it's pretty annoying to figure out the right width for each column and manually resize them and position them, so that it still looks great. Would be absolutely pitch-magic to have this automated ;-)
