Facilitating active reading of digital documents

A computer-implemented method comprising:

• displaying a first document in a first document view region;
• displaying a second document in a second document view region, wherein the first document and the second document are simultaneously visible to a user;
• receiving a hold gesture at a portion of the first document and at a portion of the second document;
• and
• generating a document object responsive to the hold gesture, the document object comprising:
• a first source link referencing the portion of the first document, wherein selection of the first source link prompts display of the portion of the first document;
• and
• a second source link referencing the portion of the second document, wherein selection of the second source link prompts display of the portion of the second document.

A computer-implemented method comprising:

• displaying a first document in a first document view region;
• displaying a second document in a second document view region;
• receiving a filtering characteristic for the first document and the second document;
• receiving a collapse gesture applicable to the first document and the second document;
• and
• responsive to the collapse gesture:
• identifying two or more portions of the first document having the filtering characteristic;
• identifying an intermediate portion of the first document positioned between the two or more portions of the first document;
• repositioning at least one of the two or more portions of the first document by modifying the intermediate portion of the first document in response to the collapse gesture;
• identifying two or more portions of the second document having the filtering characteristic;
• identifying an intermediate portion of the second document positioned between the two or more portions of the second document;
• and
• repositioning at least one of the two or more portions of the second document by modifying the intermediate portion of the second document in response to the collapse gesture;
• wherein the two or more portions of the first document are closer together after the repositioning the at least one of the two or more portions of the first document, and wherein the two or more portions of the second document are closer together after the repositioning the at least one of the two or more portions of the second document.
