Go to https://github.com/settings/tokens. Login, and allow permission to repo: Full control of private repositories. Generate a token. Copy and store this token if you will be needing it again in the future - it will not be stored in GitHub.
Clone this repo, and launch it with yarn by typing yarn start in your terminal or command line.
Enter your GitHub token in the input field, and click the button. You will see a list of repos you have access to. Click one to see its issues.
You can sort issues ascending or descending by clicking on the column headings.
File issues on GitHub or contact the developer directly.
