Let users turn the extension off temporarily for individual emails

[ProfJanetDavis]

I recently composed a email of introduction on the topic of mentoring in which I found the suggestions from Just Not Sorry very distracting. I have emailed Caren a screenshot - it's too sensitive to post here.

As a result, I would like to be able to temporarily turn off Just Not Sorry when composing a particularly difficult/sensitive email, and have it automatically start again the next time I start composing a new email.
