Gnome-Do in doesn't have the docky appearance anymore

Docky and Do were split after it became clear that the Docky theme for Do was collecting a huge amount of code not shared with anything else in Do.

The Docky found in the docky package has a large number of extra features and a huge number of bugs fixed (particularly with respect to window matching) compared to the docky theme from Do.

You will have a better dock experience with the stand-alone docky package than with the docky theme of the (previous) gnome-do package.

Docky and Gnome-Do are now two separate programs. If you want to install Docky, just go to the software center and search for "Docky" and it will come right up.

You would have to use an old and out-of-date version of Gnome Do to have them both integrated into the same application. It's actually much better that there are now two programs. You get better features and a more stable framework since Docky and GnomeDo were starting to grow into two separate entities.

Have you checked the themes for Gnome Do? Last time I used it on Lucid Lynx, on the list of themes for Gnome Do there was the dock theme available.

Docky has moved forward from Gnome Do to become a dock application only. But, as I recall the dock option is still there.
