About Auto-hide feature

I don't want to write a duplicate of another question.

However, mentioned auto-hide fetaure in the question below is not completed.

I just want to remind it.

And also my comment about it is that:

"
When I maximize a screen I don't need to look at to the calendar or any indicator.

I need to focus on my work on maximized window. And Wingpanel occupies some place although I maximize a window.
"

Keep up the good works!
