Hide details after showing them

[lightning19]

In my installer, I currently have the "Show Details" button visible, and can click that to get to the installation details.

Is there any way to get a "Hide Details" button at this point to be able to go back to where the details are hidden?

I found an old post at http://forums.winamp.com/archive/ind.../t-183437.html but it date back to 2004/2005, so I don't know where this feature stands now...
