I'm having problems with scrolling, too, but I'm not sure if it's a problem with the code being slow, or that we simply don't know how to use it.

The front page says "Click page borders and user icons for functions - feel free to experiment", but I think you need some documentation for people like me who aren't smart enough to figure out what they do. I see different colored rectangles and my cursor turns into a resize-top-border icon (??) and clicking things makes other things jump around or disappear but I can't tell where I am or what I'm doing.

A 2-minute tutorial could make the difference between "I'm confused, so I'm leaving" and "this is pretty neat". Of course, it'd be even better if it used controls that I already know how to use, so I didn't need to take a 2-minute tutorial to learn to use scrollbars again. :-)

Please use the native scrolling. It was completely unusable on a non-Safari browser on my iPad 2 (even vanilla Safari was so sluggish as to reduce any desire to use it). It looked interesting (and the comments here indicate it is), but the scrolling was so bad, I couldn't check it out.

I really hesitated to pint this out, because I hate negative comments when people throw there stuff out here, but this one is just too critical to your potential success.
