I had some confusion finding how to turn off the link to Dashboard in the widget. I would suggest you make the Dashboard link off by default, or else put the setting somewhere more visible, in next version. :)
I also suggest an option to hide the user-admin bar. That could be hard for people who don't search google all day for answers! Since all the admin bar contains (for the user, not the admin) is the profile, those same buttons are already in the widget. And the bar doesn't look great when background images slide under it, and it's in a fixed position. Plus it disapears on the logout page, creating a jumpy effect because of the 28px.
Thanks so much.
