Good to see dark mode and scientific mode both landed — those were the two things that mattered most to me. I keep a calculator in the sidebar mainly while revising maths, and being able to check a quick calculation without leaving the page I am studying on makes a real difference. The scientific functions cover the trig and log work that comes up again and again, and dark mode is much kinder during late-evening revision sessions.
One thing I would still find useful is a short history of recent calculations. When I am working through a multi-step problem, I often want to glance back at an earlier result rather than retyping the whole thing. Even a small list of the last few entries would help. Otherwise, this is a tidy little tool — simple, quick to open, and it stays out of the way until it is needed.
