To move columns to the left or right, place your mouse cursor inside any column header (while you are in the spreadsheet view) and drag the column left or right. Releasing the mouse will drop the column into its new position. Resizing columns helps you put more information of the screen. This is especially useful when you enter the split-screen mode. NutriBase also allows your to resize and/or reposition all simulteously open windows... the software will remember your last used settings for you and open windows in the size and location you specified.
