Show the value of a watched variable inline (pin a watch tooltip)

There is a new feature in visual studio 2010 - being able to "pin" a tooltip that shows the value of the variable while debugging - and the pinned tooltip is attached to a line in the source code, so that when you step through the code you see the value of the variable inline without using "watches" list.

It sounds quite useful and would be great to have it in Creator.
