Chrome 90, scheduled for release on April 13, will add the ability to label windows differently to visually separate them in the desktop panel. Support for changing the window name will simplify the organization of work when using separate browser windows for different tasks, for example, when opening separate windows for work tasks, personal interests, entertainment, deferred materials, etc.
The name is changed through the βAdd window titleβ item in the context menu that appears when you right-click on an empty area in the tab bar. After changing the name in the application panel, instead of the site name from the active tab, the selected name is displayed, which can be useful when opening the same sites in different windows linked to separate accounts. The binding is maintained between sessions and after a restart the windows will be restored with the selected names.
