I think that an ‘Open with Atom’ option would be useful in the Github for Windows client (and any other OS), so that you could open an entire repository with atom.
I, too, have been wanting this option ever since I began using GitHub Desktop.
I was surprised to see this feature missing from the Windows App, however this seems like a feature request for the GitHub Desktop app rather than atom. Is there a specific place to make feature requests for GitHub Desktop?
You can go to https://github.com/support to submit feature requests for GitHub Desktop.
Not exactly the same thing, but nevertheless useful maybe:
Add the Atom icon to your finder (if you use MacOS that is), now you can drag your project folder into the icon and your can start working.
I use this for Photoshop, Textmate etc etc.
