I have to pay you my respect. I've been watching DDG pretty much since day #1 and against all odds you've managed to both stay the course (which pretty much everybody claimed you would not) and steadily improve on it. It's one of the most impressive projects in this space, which many have tried and eventually gave up on (or compromised their ethics). Thank you.
If you disable Assist from the inline dialogue, there is a message that comes up about it, but I agree we need to show that in more places, like in the settings screen.
Maybe include it in the Assist response window? I know you can disable Assist from the settings icon there, but also including a way to avoid AI entirely where it's most relevant also seems like a reasonable approach.
