A simple chrome extension that adds the ability to search personal, starred and recently accessed repos from the chrome omnibox.
Install the extension, and access the extensions options in the chrome extensions menu Details > Extension Options or right-clicking on the extension's icon and selecting options.
Insert a valid token with the repo (for listing private repos) and read:user (for listing starred repos) permissions. Check which results you would like to appear, and the automatic update frequency.
Type gh into the chrome bar, and then either press space or tab to trigger the extension's search. Repo name and authors can be typed into the omnibox, and suggestions of repositories will be shown, and can be selected to open the url.
