A-Dock X

A-Dock X is an implementation of A-Dock for Mac OS X 10.2. It is not a remplacement for the Dock but a side-dock with some different features.

Features include a skinnable interface with customizable colors and transparency, 10-level deep folder browsing, spring-loaded folders, hot keys, and exclusion lists. In addition, it allows you to position the Dock around the edges of your screen more freely.
What's new in this version:
Fixed dummy "net" and "home" volumes that started appearing from time to time after OS X 10.6.7 update
Improved switching frontmost windows in several applications
