brent it's has nice look but too busy. I don't do redundancies anymore.
There's no task manager. I got rid of it because with the Latte dock (not Plank), it was quite redundant. You may be confusing the Workspace Switcher applet in the upper panel with the task manager. That applet is definitely not redundant, as it does a different job than the dock does. The dock launches applications, the Workspace Switcher decides where they should be launched. Apparently my explanation of that below the image fell short.
