Google's Chrome 115 has a new feature that allows users to use Windows Mica material, a design element that enhances user personalization. To access this function, users are required to go to the Chrome flags menu and activate it manually.

Mica is a distinctive design feature that doesn't just stay opaque but fuses with the user's desktop theme and wallpaper.
