Don't want minimize of current window

I work with 2 screens, and usually 3 or more open windows visible. At times, I don't know which one has focus. When I want to make sure a window has focus, I go to the taskbar 

and click that task. Unfortunately, if that window already has focus, it
gets minimized. Not what I want, ever.

I would like an option that always gives focus to the task I click.
