The mouse was built for doing one thing at a time. One cursor that navigates a rich virtual world to accomplishing things in series.

With agents my work now all happens in parallel. But the input devices we use hasn't changed yet.

What I want is not more buttons and tabs in the pixel world, but some new tactile device in the real world to jump between different virtual workflows. I want feedback about all my parallel streams of work, and direct access to them from my physical world, without dragging a cursor through many steps of virtual navigation.

And no, I don't want to learn herdr's shortcuts, on top of mac's shortcuts, on top of a keyboard not meant for this. I want a simple handheld device designed specifically for this.

My mental concept car [0] for this is a cube which lives in your palm where every stream of work is represented by a physical LED button. Tap a button to jump into the stream. Hold a button to talk to the agent in that stream. Buttons pulses when the agent needs you.
