Display coffee files on Open on Atom


When I click on Open in Atom, some packages have the coffee source while others (probably just Atom’s default packages) display the javascript compiled files (but when I explore the github repo I see only coffee files).
I understand that this is faster on run time but if I want to explore/edit/understand or simply play with the package, I would rather see the source files and have Atom compile and use the compiled files in a tmp folder.
