Currently each time you move your column widths and close out it resets to the default widths. Additionally many members of my team find it easier to use excel sheets due to the customization of these widths of rows and columns to be smaller than the current default. Right now you have to scroll more often. 

This idea is coupled with the current idea of having more than 25 rows defaulted per portfolio view. Each rep every day needs to click the 50 option and then sort through 3-4 pages which decreases adoption.
