Very good so far

Some things i noticed:

• When in fullscreen mode and page finished loading, the "exit fullscreen" button disappears after scrolling. It reappears if i scroll again, but it disappears again after scrolling finished. The button doesn't disappear if i scroll to the top of the page. Is this a bug or a feature?
  
• I tried using an url handler for youtube to watch/open in cutetube. If cutetube is not open, cutetube's display method doesn't get called. But that seems to be known
  
• Is it possible to do a page reflow, like when you press CTRL+SHIFT+I in microb?
