Dialog Improvements: maximize and restore

Hello There!
Again I made any changes on the ui dialog.
Now, i added maximize and restore original dialog.
I post two or three weeks ago, another changes on the content scroll,
resize content and etc.
Examples in: http://www.softdesign.inf.br/jquery/dialog/
Anybody can help to improve more and more this dialog?
OBS.: tem algum brasileiro por ai??? rsrs
