Is it possible to have tabs in the new windows 10 bash terminal?

It is not possible to use tabs within the Windows Command Prompt. You can use applications such as Cygwin on Windows, or Bash on Ubuntu on Windows (http://www.howtogeek.com/249966/how-to-install-and-use-the-linux-bash-shell-on-windows-10/) but I don't think that you will have Tab availability on these still.
