I would like to move the Workspace switcher icon from the bottom to the top of my Unity dock bar. Is this possible? Drag and drop does not work. Thanks!
Not for Unity (3D), not without modifying the source code. For Unity 2D, see @Matt2's answer just above or below this one.
If you want to modify the source code, download unity and look at plugins/unityshell/src/LauncherController.cpp. I don't know the exact changes required, but this answer which talks about modifications to LauncherController to remove the Workspace Switcher should give you some good hints.
