My question is related to this question: Transparent Background in Terminal?
I have successfully found the menu to change color/opacity. I used the "homebrew" profile. Then I attempted to change the opacity as shown in the answer. However, once I put the opacity at 100% and closed the window, it completely ignored my changes and went back to 90%. How do I actually ensure that my preferences are saved? There is no "OK" or "apply" button on the color menu.
