We feel UserVoice is a better platform for the over 250,000 users to get their point across to each other and vote on features that are most important to them. Issues and features will be converted to our issue list on GitHub based on importance and voting in this forum.
We track issues within GitHub, but not all users use GitHub. If you are a user of GitHub and have a major bug, feel free to track it there. All feature requests will be tracked here.
