Body: <p>Here are the columns displayed in an opening tree on ChessBase 12:</p>
  
  <p><img src="https://i.sstatic.net/GhZhw.png" alt=""></p>
  
  <p>I would be interested in adding two columns:</p>
  
  <ul>
  <li><p>A column which displays the percent of time each move is played in the position.<br>
  So for the starting position it should display something like that: 1.e4 42% - 1.d4 40% - 1.Nf3 9% - 1.c4 6% - etc.</p></li>
  <li><p>A column which displays "Perf" minus "Av".<br>
  "Av" is the average Elo before the game has started of the players who played that move. "Perf" is the average Elo after the game has ended of the players who played that move.<br>
  So "Perf" minus "Av" is equal to the average Elo one is expected to gain by playing that move.<br>
  In my opinion "Perf" minus "Av" is even more useful than the average score (the percent of time White wins plus half the percent of time it ends in a draw). And it takes me a lot of time to calculate and remember them every time.</p></li>
  </ul>

Title: In a ChessBase opening tree how can we put a column that displays the percent of time each move is played or a column that displays "Perf" minus "Av"?
