root gave us the killer SCRoot ROM with the Cookies Homescreen Mod.
It works with XDarkRoot as well and there has been a cool advancement.
The mod was always customizable via registry edits but now we have a much simpler tool thanks to johncmolyneux over at xda.

For those that love the double clock, this mod will not allow that. It may have also broken the feature where clicking on the Left of the Taskbar brings up the Program list, no biggie IMO.
All the options are listed here. The tool is supposed to restart Sense for you but I had to do it manually via Start/Settings/Today. A soft reset is not needed.
The borders of unused links can be hidden, making a clean look. Just tap Top Right to Move/Edit the links.
Enjoy.
