Support "quiet" extensions like Tranquility (if offering ad-free subscriptions is too much trouble)
The 'unobtrusive' ads in the browser version are actually quite distracting to me. Happy to pay a small monthly fee, but if you could set your pages to display synonyms when quiet reader extensions are invoked, that would suit me fine. Currently, when I turn on Tranquility in Firefox all I see is the count of synonyms and a copyright notice. If I have a way to see results without ads, I promise to donate.
