Mirror-like auto-completion pop-up when there is no space above the cursor!

[ghost]

Hey guys.

I like the superTab mechanism in navigating the completion menu from bottom to top, but there is a matter with this!
Actually when there is no space above the cursor (e.g. in line 1) the menu appears down and the nearest option is at the bottom of the list so watching the option at a glance is a little painful in this position!
So is there any way to setting superTab plug-in to act like a mirror in this position? (I mean the order of the options in list being reversed, so that it can be seen so painless and quickly.)

Regards.
