There is a bug where when I scroll to the next page, all the old text from the previous page still shows. (using latest firefox on OS X)

It would be nice to use this method with some texts I want to read...but definetley not all.

Can't scan.

Probably would be really good to read an academic paper I really want to grasp a second time.

Good experiment!

Edit: (Since it said it was Chrome only...tried it with Chrome, text from previous page still shows up...)
