Abstract: A computing device displays electronic content associated with a plurality of annotations each corresponding to a respective portion of the electronic content. A first annotation, which includes one or more comments associated with a first portion of the electronic content, is displayed. While the first annotation is displayed, an input to display a second annotation is received. The second annotation is associated with a second portion of the electronic content, and includes one or more comments associated with the second portion. Responsive to receiving the input, the second portion of the electronic content and the one or more comments associated with the second portion are displayed.
