Extension needs to be more responsive
When I'm on a smaller screen, I can't see half of the extension and I can't scroll either.

Looking at the screenshot, I think this has been fixed by #181.
That means, a simple rebuild will be sufficient to resolve this issue.
That would definitely help. I think also the code area doesn't need to fill half of the visible space. Most of the time there's only a single line there. Maybe two or three.
With queries that's definitely true. But will that also be true when writing user-events?
I'll look into it. Maybe it's possible to make it auto grow on smaller screens. Or 1 - 2 lines by default, with an expand button that makes it grow to the current 50%. That would solve the screen size issue.
Yeah, I think we could get creative
