I have a Rails application that performs an expensive operation. I do not want to sit and wait for it to complete. I want to work on other aspects of the application, as the expensive operation is done. Consequently, I want to be able to launch the project on a different ports e.g. port 3000, another on port 3001, just as I could do it in terminal. But when I try to open the project again using File > Open, it just returns back to the currently opened project. How can I open same project in different windows and run the rails server in each different window?
