Width of content too cluttered
Simply put, long gone are the days of essentially square CRT monitors. Today's flat screens are wider than higher. And the screen space is not getting used effectively by the board software; indeed, the output is crunched and cluttered.
For example, my monitor winds up with 3.75" left border, a 11" width for text , and a 3.75" right side border. In other words, a 40% waste of space.
