Please install it if you are working on Github pull requests. It shows which lines of code are executed and which are not, and so is invaluable for developing and reviewing PRs.

Unfortunately their Firefox support is broken since quite a while https://github.com/codecov/browser-extension/issues/44.

While we're at tooling, https://octobox.io is fairly nice to manage the
GH notifications in an E-Mail Inbox like manner.
A direct GH IMAP integration would be even better still :o.

And on another point, we'd still like you on our dlang slack @Walter.
It's fairly low traffic but a useful tool for informal questions and pings.
