It is advisable to remain measured, because this feature is currently no official or documented by Microsoft in the version of its Builds Insider. Its integration as hidden functionality suggests an early testing phase. There is no guarantee that it will be deployed in the final version of the next major Windows 11 update.
This novelty is added to a series of constant adjustments that Microsoft brings to its operating system. Recently, it was the file explorer that had been the big winner of the latest Windows 11 beta, proof that the company continues to refine the user experience in small touches. Audio sharing is part of this logic of continuous improvement in the quality of digital life.
Moreover, this same experimental build introduces another, more subtle modification concerning the interface. The taskbar benefits from new animations when flying over open applications icons. Windows overviews are now dynamically adjusting to their actual size with a new transition animation, making navigation more fluid and consistent.
