Theming: Ability to set background transparency / transparent / opacity

[domderen]

Is your feature request related to a problem? Please describe.
I normally set my terminal to have a semi-transparent background, to be able to see windows beneath it. This allows me to see a website with an article or a tutorial in the background while still being able to work in a terminal. It's much easier than switching between windows.

Describe the solution you'd like
Add the ability to set background transparency.

Additional context
I usually work just on my laptop, no external monitors.
