You can show/hide terminal windows with a hotkey natively using iTerm2.
Under Preferences > Keys > Hotkey I've set the system-wide hotkey to option+space which means if I need a terminal, I can press those keys and have iTerm pop up over my active window.
Pressing them again hides the window and brings focus back to the previously active window which has been great for productivity.
