Favourite WLM Features / Moments

Anyone Got Any Fond Memories Of WLM Or Favourite Features? They Liked?

My favorite feature was the Photo Gallery and the embedded videos. I mean when you inserted for example a YouTube url, then you was able to play the video next to the converstaion window at the same place as shared photo gallery without opening/switching web browser tab.

Good thing, I was told about WLM 2009 already did support the photo sharing.
