While Microsoft has been improving the features and introducing new features in every Windows 10 build, Microsoft Edge is also evolving with new features. Although Reading View was included in one of the previous builds, with the 18945 build it has been enhanced by including the line focus feature. Line Focus enables one to really focus on what he/she is reading.
