- Moved the cell toolbar selector into the *View* menu. Added a button that triggers a "hint" animation to the main toolbar so users can find the new location. (Click here to see a `screencast <https://cloud.githubusercontent.com/assets/335567/10711889/59665a5a-7a3e-11e5-970f-86b89592880c.gif>`__ )
- Added *Restart & Run All* to the *Kernel* menu. Users can also bind it to a keyboard shortcut on action ``restart-kernel-and-run-all-cells``.
- Added multiple-cell selection. Users press ``Shift-Up/Down`` or ``Shift-K/J`` to extend selection in command mode. Various actions such as cut/copy/paste, execute, cell type conversion, and so on now operate on all selected cells.
- Added a command palette for executing Jupyter actions by name. Users press ``Cmd/Ctrl-Shift-P`` or click the new command pallete icon on the toolbar.
