While watching a game

A game is on, players are still making moves. I want to look at a position from 3 moves ago. I click that move on the notation box. When a player makes a move the game switches to the last move. Then I have to go back that move and then they make moves again.

For players like me (1300-1400 pt.) or below can not visualize or analyse on our minds, we have to see the position.

So when we chose a move in the notation box, the position should stay. When players made a new move, there should be a button("live", "new move made" sth.) appearing, when clicked goes to last position.  

Also there should be a button to close the chat window for sometimes people are troll-racing 

I Agree!!!
