A

• non-transitory computer readable storage medium comprising:
• first program instructions to display, by an application, same data of a unit of information in a first window and in a second window on a display, wherein said same data of said unit of information is not frozen in said first window and in said second window;
• wherein said second window comprises a freeze control;
• second program instructions to, in response to said application receiving an activation of said freeze control in said second window, freeze, by said application, said same data of said unit of information in said second window, wherein said same data of said unit of information in said second window is frozen data;
• wherein said same data of said unit of information in said first window is not frozen in response to said activation of said freeze control in said second window;
• third program instructions to, after said freeze, in response to said application receiving at least one edit to said same data in said first window, modify, by said application, said same data of said unit of information in said first window in accordance with said at least one edit, wherein said application does not apply said at least one edit to said frozen data in said second window, wherein said frozen data in said second window and said same data that is modified in said first window are concurrently displayed by said application;
• and
• fourth program instructions to, in response to said application receiving an activation of a thaw control in said second window, modify, by said application, at least a portion of said frozen data of said unit of information in said second window on said display in accordance with said at least one edit;
• wherein said first, second, third, and fourth program instructions are stored on said non-transitory computer readable storage medium.

A system comprising:

• a processor;
• and
• a memory storing instructions that are executable by said processor to:
• display, by an application, same data of a unit of information in a first window and in a second window on a display, wherein said same data of said unit of information is not frozen in said first window and in said second window;
• wherein said second window comprises a freeze control;
• in response to said application receiving an activation of said freeze control in said second window, freeze, by said application, said same data of said unit of information in said second window, wherein said same data of said unit of information in said second window is frozen data;
• wherein said same data of said unit of information in said first window is not frozen in response to said activation of said freeze control in said second window;
• after said freeze, in response to said application receiving at least one edit to said same data in said first window, modify, by said application, said same data of said unit of information in said first window in accordance with said at least one edit, wherein said application does not apply said at least one edit to said frozen data in said second window, wherein said frozen data in said second window and said same data that is modified in said first window are concurrently displayed by said application;
• and
• in response to said application receiving an activation of a thaw control in said second window, modify, by said application, at least a portion of said frozen data of said unit of information in said second window on said display in accordance with said at least one edit.
