Abstract: A method for maintaining revisions for a plurality of documents is described. Pending requests are stored in a workspace revision queue that is shared by the plurality of documents. The pending requests indicate revisions to be carried out on the plurality of documents. A pending request graph is generated for at least some pending requests from the workspace revision queue using a dependency graph for the plurality of documents. The dependency graph represents interdependencies of content references among the plurality of documents. The revisions indicated by the pending requests of the pending request graph are caused to be performed on the plurality of documents according to a dependency ordering based on the pending request graph. The dependency ordering is different from an ordering for the workspace revision queue.

Abstract: A method for filtering a set of records on a user interface involves displaying a set of records, each record of the set comprising a first field and a second field; removing, from the displayed set, one or more records according to a filter of the first field, thereby leaving a subset of the set of records displayed; displaying filters for the second field; and for at least one of the displayed filters, visually indicating that, due to a currently-applied filter, the at least one displayed filter does not apply to any of the records of the subset.

Abstract: A computing device (e.g., a processor executing instructions on the computing device) receives an input (e.g., from a user or from a data stream) into a cell of a table (e.g., a cell of a spreadsheet, worksheet, or workbook). If the input is a sum (e.g., a formula whose result is the sum of previous cells), then the computing device renders a total column representing the sum on a waterfall chart (e.g., on a user interface rendered on an electronic display). Otherwise, if the input is a static value (e.g., an integer or decimal number), then the computing device renders a change column representing the static value.
