ObjectBar 1.0 came out and has been quite a hit with over 80,000 downloads. But Stardock wasn't entirely happy with the release. It felt it was too slow, too buggy, and too hard to use.
Version 1.1 addresses some of this with a much more stable, faster version of it that uses considerably less memory.
What's neat about ObjectBar is that it is so flexible that you can make a bar that looks identical to the Windows XP Start bar (on Win2k) that also has the features of it. At the same time, you could create a MacOS X-like "Finder" bar that strips out the menu bar. Basically any bar, wharf, finder, dock, etc. ObjectBar can do plus create any combination of them.
And as if all that's not enough, it's skinnable too.
Version 1.1 also includes full documentation on the ObjectBar website and information on its use.
