8 Visual and Audio Layout and Feedback Extensions

Several extensions exist that can be used to add various forms of visual or audio feedback to the notebook user interface.

These extensions might be used in part to help maintain a sense of situational awareness about the state of the various cells.

8.1 Cell Execution Status

The nb_cell_execution_status extension uses colour in code cell gutters to indicate the run status of each code cell:

• white: not executed
• light cyan: awaiting execution
• green: successfully executed
• pink: failed

This provides useful feedback on which part of the notebook has been run during a notebook session.

Audible feedback for successful and unsuccessful cell completion can also be enabled from the notebook extension configurator menu:

8.2 Two Column Display

The twoCol extension provides a toolbar button that will toggle the display of a selected code cell from a one column to a two column display, allowing the code cell output to be displayed alongside, rather than below, a code cell.

For feature requests relating to further development of this extension, please file an issue on the repository.
