Oh wow, this reminds me of the good ol' ExtJS desktop demo: http://extjs.cachefly.net/ext-3.4.0/examples/desktop/desktop...

Around 2006 these "desktop" webapps was getting popular, there are some with even more comprehensive features (for its time) which I forgot the name (probably OnlineOS, can't verify it because it's dead: https://en.wikipedia.org/wiki/Online_OS).
