When editing the profiles.json settings file, it is currently not possible to specify more than one defaultProfile. As a result, it is not possible to have the Terminal automatically start up with more than one tab. It would be extremely convenient, to be able to specify the 3 or 4 most commonly used command-line environments to all open up in separate tabs every time Terminal is started. This would e.g. give users the ability to always open up a Command Prompt, PowerShell, and Ubuntu shell all at the same time.
