Ever since I started looking at Magit as a "git dashboard" instead of as a "git interface" it's been yet another Emacs killer app to me. I just recently started playing with forge which allows Magit to interface and interact with git "forges" like GitHub. This allows you to work on issues and pull requests without ever leaving Emacs.

Here's a video on how easy it is. The video doesn't show this but the first time you fire forge up it will prompt you for credentials.

Also, if you aren't familiar with GitHub issues, check out the post/video I made a few days ago (link) and you can check out my earlier post/video on Magit as well (link).

Enjoy.
