Additional trackpad gestures

Hey everyone,

I am a pretty new Mac user though I like the trackpad gestures. However two important gestures are missing in my opinion, close an application or window and create a new one, e.g. in Firefox new window apple + n and close window apple + w.

I want to have these shortcuts done with the trackpad gestures, I have read xGestures is a possibility, is this right? Are there any FREE alternatives. Can't be the case that I am one of the only few requesting such a feature.

thank you for your help

 

The boastr thing is really perfect! I can definately recommend it, alot of options and really nice handling. Thanks for the fast answers.
