Whenever I open the terminal a new window automatically opens up, I'd like to turn it off so that when I open the terminal I don't get a window and have to manually choose one from the shell menu.
The reason is that I'm opening a 3rd party application which opens an REPL in the terminal, and thus when the app opens the terminal I get two windows, one is the REPL which I want, and the other is another default window which I don't.
