LGTM. I did flag an (existing) issue with the badge status label essentially resulting in an empty i18n message when running npm run i18n_extract. I defer to you whether you'd like to address that in this PR; otherwise, we could consider flagging it to Markhors since they are working on the i18n stuff.
