Is it possible to move the Gnome Shell dock extension over to the left and disable the autohide?
A new modified version of the Gnome Shell dock extension has been made by xeXpanderx that sets the dock to bottom by default.
The original dock extension by gcampax can only be set to left or right edges of the screen.
