This plugins adds a command to the heroku cli, so you can run other command always with the same global options.
This is really helpful when you have multiple applications in the same project/folder.
Let's say you have app1-prod and app1-stag.
Now you can say:
heroku prompt --app app1-stag
This will open a new prompt where you can enter any heroku command and be sure that all will be runned on the app1-stag application context.
