jQuery UI Dialog Extra
jQuery UI Dialog Extra adds minimize/maximize/restore buttons to standard jQuery UI dialog.
See demo.html for details.
I don't maintain this project anymore. I decided to move it to GitHub to give other people an ability to fork it and use it.
P.S. Thanks to Joan Molina from http://www.uic.es/ for iframe bug-report and fix.
P.P.S. Dont look into the code. I know it is weird (:
