HistA wot OTWL

HistA is a browser extension designed for students using McGraw Hill Connect.
It re-enables spell check and autocorrect on fill-in-the-blank input fields
that have had these features disabled by the platform. Simply click Enable
Spell Check and HistA will automatically apply spell check to all input fields,
even as new questions dynamically load. Includes a Challenge Mode which
randomly toggles spell check to keep you on your toes, multiple colour themes,
and persistent settings that save across sessions.
