Where to start. YOU HAVE TO TRY IT. A 100% working computer in Vanilla, just an amazing job, I find it even strange that it is not a paid plugin. The community can develop their own applications although it already includes a video player, an online search engine and even a NES emulator.
The support is simply 12/10, answering fast and completely responsive to get you up and running if you have problems and improve the plugin.
Undoubtedly a great programmer who makes things that seem like dreams come true.
