Microsoft introduced the Windows Overlay function, which provides advanced web application developers with additional tools to manage the title line. This means that in Windows, they will become more similar to the actual software.
To date, the web applications have not had access to the title line, which has had unpredictable consequences: the creation of empty spaces, the conflict of flowers and other errors that have caused PWA to differ dramatically from the traditional software. With Windows Controls Overlay, all these problems have been left behind: developers have gained access to the "all surface" of the application window; only the area in the upper right corner where the window control buttons are located cannot be adjusted.
Microsoft originally proposed this function in January 2020, showing its work in a demonstration web application. Support for Windows Overlay in Chrome appeared in April 2022 as a beta function, and in August with the release of Chrome 105, the feature was released.
