Delphi. UniGUI. Desktop

Вчера увидел на форуме UniGUI интересное приложение, написанное одним из участников из Бразилии, выглядит оно вот так…

То есть, по сути, это рабочий стол в браузере – на мой взгляд, интересный вариант интерфейса для веб-программ. Посмотрел исходный код – ничего сложного, полностью написано на Delphi UniGUI.

Единственное, что пришлось поправить, это номер версии ExtJS, по аналогии с постом на форуме. Так как автор писал на предыдущей версии UniGUI.
