The free MDITabs Bonus Tools from Autodesk , as reported by Shaan Hurley, Autodesk Blogger of Between The Lines, will work with AutoCAD 2011! I've used this tool in the past and just might download it again, now that it seems to work with 2011.
Go on over to his site to check it out and to download it.

Thanks Shaan for trying it out for us.
