Great plugin I ran into that is perfect for MU

So I'm doing a new WP install today and I happened to notice all these red icons everywhere in the default theme.
It is a new WP voice tutorial plugin called sidekick.
This is perfect for all my new users on MU that do not yet really know how to get around WP very well.
I am looking forward to how they increase the functionality....so many possibilities here.

I thought I would share this with the group
