Where would you expect to find the button to log out: in the side menu or under settings?

Side menu first. Settings second.

It’ll be in the Setting menu in the next build! #[4] are you 👍🏻 for side menu too?
The reason I didn’t add it there in the first place is that we show a warning to make sure the user backs up their key, and from the side menu it’s less obvious where to do that than in Settings (where it is right next to the logout button).
