iTerm isan application brings the terminal into the modern age with features for macOS powdered computers. With iTerm, you can divide a tab up into multiple panes, each one showing a different session. You can slice vertically and horizontally and create any number of panes in any imaginable arrangement. Notice how inactive panes are slightly dimmed so it's easy to see which is active. Register a hotkey that brings iTerm2 to the foreground when you're in another application. A terminal is always a keypress away. You can choose to have the hotkey open a dedicated window. This gives you an always-available terminal (like Visor, Guake, or Yakuake) at your fingertips. iTerm also provides search and find-on-page feature, allowing you to immediately highlight matches and navigate your terminal faster.
