Is this a new feature, or had I simply not noticed before?

In the game view, Details tab, there's "Show rating adjustment" An excellent feature, if I see that I'm going to drop lot's of points, it really gets me re-enthused about making sure to win the game.

I like it. 

It's a recently added feature. It certainly makes decisions like playing for a draw or a win easier to make.

It also makes me somewhat more cautious when starting new games.  If I'm going to play a person and risk losing ~70 points for a lose, ~35 for a draw, and ~10 for a win, I don't want to take my chances, as there are several instances while playing on chess.com I'm having a bad day or don't think through my moves...

Maybe it's just because I get an idea of what kind of chess player you are from your online chess rating, so I want mine to look good.
