Hey guys , I would like to know is there a dock that does the minimization perfectly ?

Like when you minimize a window the thing will 'wave' into the dock.

The RKLauncher does that but not every window will 'wave', plus it is buggy like sometimes it duplicates the windows in the dock, where it only has one window.

Is there a perfect one ? If not I will rather use a dock that does not do the minimization thing since there is no point having one that does minimization on some windows but not all.
