Why have one specific package for opening the current project in the terminal, another one for the Finder and a third for the GitHub application when you know which applications you use?
Open In is a package for opening the current project or file in the application of your choice.
apm install open-in or search for it in the package manager.
ctrl-alt-o and pick project or file, then the application of choice.
A comma separated list without spaces of applications you want to be able to trigger.
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
