0.10.0 - phones, and taking turns at the keyboard
Two things: phones, and more than one viewer.
Touch mode. A phone has no pointer to map, and pretending it does made the console unusable. On a touch screen the picture is a trackpad now: one finger moves the pointer, a tap is a left click, two fingers tapped is a right click, two fingers dragged scrolls, a long press then drag holds the button down. The on-screen keyboard types through the target's own layout, the way paste already did. It switches itself on when the browser reports a coarse pointer, and there is a Touch button when it gets that wrong.
One driver at a time. Until now every new viewer quietly took the keyboard from whoever had it, and the one who lost it was not told. The first client holds control now and keeps it. A second viewer gets a banner saying somebody else is driving, with a "Take control" button. Taking control drops the previous holder to a viewer instead of throwing them out, so they keep watching and can ask for it back.
