Systems and methods are disclosed for sharing a unified undo/redo stack between multiple applications. A method determining that a host application receives an action regarding a document, adding the action to a unified stack that is associated with undo commands and is shared between the host application and a secondary application, receiving an undo command from the host application or the secondary application, and retrieving the undo command from the unified stack to cause the action to be undone in the host application and the secondary application.

Systems and methods are disclosed for providing a summary of suggested changes made to an electronic document. A suggested change is iteratively selected from a first list of suggested changes. A second list of modified suggested changes is generated by processing each selected suggested change in the first list of suggested changes. The processing comprises marking the selected suggested change for including or excluding the summary. If the selected suggested change is marked for including the summary, the processing further comprises at least one of combining the selected suggested change with a previously processed suggested change to form one of the modified suggested changes for including in the second list, and truncating the selected suggested change to form one of the modified suggested changes for including in the second list. The second list of modified suggested changes is provided as the summary of suggested changes.

Systems and methods are described that include providing, on a touchscreen display of an electronic device, a stream of content items, at least some of which are associated with a corresponding display anchor. Inputs are detected at the touchscreen display and the inputs are associated with a scroll speed. The scroll speed may be based on a detected distance between the inputs on the touchscreen and an elapsed time between at least two of the inputs. In response to determining a lack of input for a predefined time period, a display anchor can be determined and selected. The display anchor may correspond to a content item to be used as a pause location for the stream. The scrolling of the stream of content items can be paused at the pause location to use the selected display anchor to display the content item in a top viewable portion of the display.

Automatic positioning of content items in a scrolling display for optimal viewing of the items

A plurality of objects associated with respective footnote reference information within a document are generated. An overflow object associated with overflow footnote reference information corresponding to a previous footnote marker appearing on a previous page is invoked to lay out the overflow footnote reference information, generating overflow layout data. A current page object associated with current page footnote reference information that corresponds to a current page footnote marker appearing on the page is invoked to lay out the current page footnote reference information, generating current page footnote reference information layout data, if an available footnote height is sufficient to lay out the current page footnote reference information. The page is displayed based on the overflow layout data and the current page footnote reference information layout data.

A document editor may manage suggested edits in a collaborative document. The document editor may instantiate a document model associated with the collaborative document. When a first editing suggestion is received for the collaborative document, a first suggestion command is associated with the first editing suggestion based on a type of the first editing suggestion and a type of the document model. The document editor may apply the first suggestion command on the document model to present the first editing suggestion within the collaborative document. When an acceptance indication for the first editing suggestion is received, the document model can be updated with the first suggestion command in response to the received acceptance indication.

Systems and methods of pasting a discontinuous selection from a first document are provided, comprising receiving, at a processor, the discontinuous selection modeling the selection as a data structure, and pasting each of the plurality of portions including contextual formatting for each portion. The discontinuous selection includes a plurality of portions of the first document and the portions are discontinuous. The portions may include one or more cells from a table, and pasting the one or more cells includes pasting at least borders of the cell, a background color of the cell, and text contained in the cell.

Method for creating a document model from discontinuous selections of an existing document

A list indicating positions of positioned elements on a page of a document is maintained by a page object associated with the page. First position information indicating a first position of a first positioned element having a position that conflicts with a location of a first element associated with the page is transmitted by the page object to a first element object associated with the first element, the first element object being subordinate to the page object within a hierarchy. The first element object generates first layout data. The list is updated by the page object based on a position of a second positioned element having a position that conflicts with the first element. A second element object associated with a second element associated with the page, and subordinate to the page object within the hierarchy, is invoked by the page object to generate second layout data.

System and method for maintaining position information for positioned elements in a document, invoking objects to lay out the elements, and displaying the document

Solutions, systems, and techniques for applying 2-dimensional changes to a shared document are discussed. The document is divided into vertical columns of a particular width, each column represented as a one-dimensional vector that is a sequential list of blocks in that column, each block representing a content item included in the document. Each block has a starting column, a block height, and a block width indicated by how many columns the block occupies. Each block has row indexes that represent a relative position of the block in each column it occupies. A document modification command is represented as transfer functions, each transfer function corresponding to a document column. The transfer functions are applied to the document columns to alter a row index of block(s) in the corresponding column(s), thereby altering the relative position of a block with respect to other blocks in that column.

Operational-transform-compatible representation of 2-dimensional page layout data

Data defining a document is received from an online document processing service, and a plurality of elements within the document is identified. The plurality of elements may comprise paragraphs, lines of text, images, tables, headers, footers, footnotes, footnote reference information, etc. For each of the plurality of elements, a respective object comprising a layout function and a render function is generated. An object corresponding to an element is invoked to generate layout data associated with the element, and the element is rendered based on the layout data.
