“Few days back, the team made available a new UI specification
document for multi-monitor setups. These specifications will be
tested by prototypes and one such prototype for launcher reveal has
been released.“The team is exploring having a Launcher on each display. The
motivation for making the Launcher available from any display is to
allow the user to launch and switch applications, without having to
travel onto another display to do so.”
