Does it have a . Hotkey for automatically switching to the next idle worker, like the namesake did?

I'm also seriously considering the ability to produce aoeii sound effects like "nuh nuh nuh"

It does not. I opted for the flow of returning to dashboard to give the user the control over which context they wanted to launch themselves into. I'm not against considering the feature, but in my own work trying to wrangle multiple agents, I haven't found the idle worker switch feature to be something I wanted personally
