There's an open issue for one thing I notice all the time: the next/previous unresolved commands update some internal state but scrolling and other navigation do not. This means that if you use any other navigation mechanism (e.g. search) the next time you hit “go to next unresolved” button it will instead scroll backwards to whatever thread follows the last one you navigated to using the “go to next unresolved” mechanism even if that's scrolling hundreds of lines back.
