GitHub handshake Gitlab
If your GitHub issue is waiting on a Gitlab issue simply add this comment to your GitHub issue:
- @SnoozeThis https://gitlab.com/url-of-gitlab-issue
You can then forget about the issue and move on. SnoozeThis will monitor the Gitlab issue and notify you (by adding a new comment) once the Gitlab issue has been completed.
No need to install anything (though our app unlocks additional features and enables snoozing on private repositories).
