Hi @tev thanks for your patience! We know it's been a bit since you submitted.

Could you please provide a learn-more section to your store.md page (prehaps to the Crawler's Companion web app?).

We would also need you to squash these commits into one commit.

Since this is an extension wrapping another person's web app could you please send us proof of permission to [email protected]? We'd just like to confirm that this is all good before adding it here :)
