Appreciate the thorough review, TheInfidel.
Duly noted, regarding the paywall. As you may conclude from that, I am not really pushing people to upgrade to Pro. It's more of a support the development - type of thing.

Aside, I did not want to bloat the extension size by adding a bunch of text into the Popup window. At some point, I might describe it a bit better and have a page dedicated to the features and pricing, before authentication lock.
