After loading the extension, only newly executed cells are affected. Previous tracebacks will remain visible until the corresponding cell is executed again.

If you press the button on the toolbar with the exclamation mark, you can turn on tracebacks again.

Internals

This extensions works by overriding the OutputArea.prototype.append_error function, replacing it with a new function that only displays the error type and message.
