Hi @peternlewis, I'm wondering if this is a bug or just something with my setup.
As you can see in the screenshot, certain actions with text entry areas don't change their background color when the OS is set to dark mode. I've only noticed it with the Insert styled text by pasting and Display text in a window actions so far.
Not a big deal, but I hadn't noticed this before so I figured I would report it.
Have a great day!
