Analysis Board

I know the chess.com staff are very busy and can't just implement people's ideas on a moment's notice, but I had an idea that chess.com might use sometime in the future:

        When I'm playing online chess, I almost always use the analysis board for every move, because it's convenient to be able move the pieces around. However, if you are trying different moves in a position, each time you input a new move the other moves you analyzed are erased. So, I was wondering if there was a way to show your variations in the move list and view them later, so if I want to return to a position I analyzed I don't have to start over?

Good idea, I have the same problem.

Glad I'm not the only person who's thought of this.

All of the features you mentioned would be helpful.
