Pretty cool with the editor interaction.

Also worth bearing in mind most shells can do this sort of thing easily enough too.

The example from your video with zsh's zmv (bundled: https://github.com/zsh-users/zsh/blob/master/Functions/Misc/... )

  > touch btn_google_{signin,signup}_dark_normal_web{,@2x}.png # create files
  > ls -l
