Hi, thanks a ton for the detailed feedback; it really helps us improve.

Because of your review we have now marked Caramel as Open Beta. This makes it clear the extension is still in active development, though it can already land valid coupons when available.

At the moment we pull codes from public sources but do not verify them automatically. A rating and voting system to weed out expired or private coupons is high on our roadmap.

We never meant to be intrusive. In our next release, the animated pop-up will now appear only the first time you use Caramel on a given site, and a new setting will let you disable it entirely.

Thanks again for highlighting what works (speed, privacy, no login) and what needs work. If you have more ideas, feel free to open a GitHub issue, every report shapes the next release.
