Alternate SB Docks for iMatte v5
This will install 4 additional docks. Alt Dock 1 and Simple Dock is made by me, and Alt Dock 2&3 by @Zooropalg.
Usage: Enable anywhere above the main theme in Winterboard. You may also want to enable it above your springboard layout, if it's already replacing the dock.
You can install independently of the main theme.
