Anchoring viewport

A method, comprising:

• at an electronic device with a display:
• displaying, on the display, a first subset of graphical representations of data objects in a collection, wherein the graphical representations of data objects in the collection are arranged in an order;
• while displaying the first subset of graphical representations, detecting a change in the collection of data objects;
• in response to detecting the change in the collection of data objects:
• in accordance with a determination that the detected change is associated with a location above the first subset of graphical representations, wherein the location above the first subset of graphical representations is a location in the collection that is not currently displayed:
• configuring a layout of a second subset of graphical representations of data objects in the collection, wherein the second subset of graphical representations does not include any graphical representations of the first subset of graphical representations in accordance with the detected change in the collection, so that one or more graphical representations above the first subset of graphical representations are arranged in a first direction starting from an anchor in the first subset of graphical representations;
• and
• maintaining the display of the first subset of graphical representations on the display in the same arrangement as before the detected change;
• and
• in accordance with a determination that the detected change is associated with a location after the anchor and in the first subset of graphical representations:
• configuring a layout of graphical representations in accordance with the detected change;
• so that one or more graphical representations after the anchor in the first subset of graphical representations are arranged in a second direction starting from the anchor in the first subset of graphical representations, wherein the second direction is different from the first direction.

An electronic device, comprising:

• a display;
• and
• one or more processors coupled to the display, the one or more processors configured to:
• display, on the display, a first subset of graphical representations of data objects in a collection, wherein the graphical representations of data objects in the collection are arranged in an order;
• while displaying the first subset of graphical representations;
• detecting a change in the collection of data objects;
• in response to detecting the change in the collection of data objects:
• in accordance with a determination that the detected change is associated with a location above the first subset of graphical representations, wherein the location above the first subset of graphical representations is a location in the collection that is not currently displayed:
• configure a layout of a second subset of graphical representations of data objects in the collection, wherein the second subset of graphical representations does not include any graphical representations of the first subset of graphical representations in accordance with the detected change in the collection, so that one or more graphical representations above the first subset of graphical representations are arranged in a first direction starting from an anchor in the first subset of graphical representations;
• and
• maintain the display of the first subset of graphical representations on the display in the same arrangement as before the detected change;
• and
• in accordance with a determination that the detected change is associated with a location after the anchor and in the first subset of graphical representations:
• configure a layout of graphical representations in accordance with the detected change, so that one or more graphical representations after the anchor in the first subset of graphical representations are arranged in a second direction starting from the anchor in the first subset of graphical representations, wherein the second direction is different from the first direction.
