Added undo for the last correction, keyboard-accessible suggestion controls, “Ignore for session,” and locally stored personal typo-to-correction pairs.
Typo.js is now an exact, unmodified copy of official npm release 1.3.2. All spelling and writing checks remain local; no writing is transmitted or logged.

Fixed a suggestion message that could remain visible after correcting text or closing an email
editor.
Messages can now be dismissed with the close button, the badge, Escape, or by leaving/
removing the editor.
