Disable "Power off" feature

yes,

What I mean is to disable this page/feature. So that when I double click on the speed dial page, this page won't come out.

click on the checkbox  bottom right corner 

Oh, but this only hide the textbox.
What I mean is a option to completely disable "double click to hide dial"

So whenever I double click the speed dial page, nothing would happen. The speed dial page is not hidden and stays the same.

Because I rarely use this "power off" feature and I always accidentally hide my speed dial page.

This is the only what we got right know. We will think what we can do here...

Thank you!
