Google wants to let you use your phone as a remote Googlebook trackpad

Google is exploring a new feature that allows Android phones to function as a remote trackpad for Googlebook devices via a Cast trackpad option. Separately, users can now utilize wired headphones without sacrificing their device's charging capabilities. This is achieved through the use of simple pass-through adapters, which enable simultaneous audio playback and battery charging. These developments offer enhanced control for Googlebook users and improved hardware flexibility for those preferring wired audio over wireless options.
