The tiniest of feature requests – could the “Repository transfer” email contain a link to the new repository? Currently those emails read:
Hello [org] Owner, [user] has transferred the [other-org]/[repo] repository to [org]/[repo]. No further action is required at this time. Questions? Problems? Please contact firstname.lastname@example.org any time. Thanks, Your friends at GitHub
[org]/[repo] are plaintext, as is the whole email (it’s not multipart html) so it’s a bit fiddly to get to that repo, especially on mobile.
