Design tool for arranging objects and adjusting spacing in a layout

One or more non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform functions comprising:

• providing one or more instructions configured to cause a display device to display a first arrangement of a plurality of objects;
• receiving input that selects the plurality of objects;
• determining whether the first arrangement of the selected plurality of objects satisfies criteria for being treated as an organized collection, in which each object of the selected plurality of objects is included in one or more lists;
• wherein the criteria include:
• within each list of the one or more lists, overlap along a first axis of each object in a respective list, and uniform spacing along the first axis between each object in a respective list;
• and
• when there is a plurality of lists, uniform spacing along a second axis between lists of the plurality of lists;
• and
• in response to determining that the first arrangement of the selected plurality of objects satisfies the criteria for being treated as an organized collection:
• allowing operations on individual objects within the concurrently selected organized collection of the first arrangement;
• and
• in response to an allowed operation that would violate one or more of the uniform spacing along the first axis between each object in a respective list or, when there is a plurality of lists, the uniform spacing along the second axis between lists of the plurality of lists:
• generating a second arrangement of the selected plurality of objects by performing the allowed operation and automatically adjusting spacing to maintain, within each list, uniform spacing along the first axis between each object in a respective list, and to maintain, when there is a plurality of lists, uniform spacing along the second axis between lists of the plurality of lists;
• and
• providing one or more instructions configured to cause the display device to display the second arrangement of the selected plurality of objects.
