Whats your fav. XBMC script/feature?

[axisds]

It has been brought to my attention that there is a pretty good XBMC crowed on here. So I was wondering if we could all share the love on what their favorite script or feature they added. There may be a few things some of us have added that others don't have.

I personally am looking for a way to download BitTorrented tv (battlestar gelactica) shows with XBMC. Any ideas?
