I've noticed that when I use the Messaging sidebar in "Outlook.com/Hotmail" and "People", it doesn't show the list of my recent conversations.
Only the "Start new conversation" thing and then blank.

But when I use "Skydrive" there it is, it shows the list of my recent conversations.
It bothers me. Haha. :)

Also I think it would be nice if the Messaging will have it's own notif sound.
Just add an on&off option. :)
Yay!
