I'm not sure if this is already possible, but something I don't like right now is that I have to switch back and forth between lenses for certain types of questions. I use Kagi a lot for research so I'm always going between different domains, and it feels like it would save a few seconds if there was a way to pass a parameter to select lens in the URL.
Specifically, I think the workflow with Quick Answer would become faster. Right now, you have to switch lenses and then hit quick answer again.
