Honestly, the site has somewhat of a crackpot-vibe. Only major feature I understand from the site is "visible links", i.e. links displayed as actual lines on the screen. This seems more like a gimmick than a ground-breaking fundamental difference from the Web. Some of the features you mention could perhaps be useful if implemented in a browser extension, e.g. the ability to see/preview linked documents inline. It is useful in IDE's for code navigation, so perhaps also in a browser.
