Microsoft is rolling out a preview of the Windows Terminal v.0.3 console application with a long list of improvements and bug fixes. Windows Terminal is an open-source terminal application that was announced by Microsoft at the Build developer conference in May 2019 and launched in June. The latest version of Windows Terminal comes with an updated interface that can be dragged from anywhere, but the draggable area is still limited to the right side and portion gets smaller when more tabs are open. Microsoft has also improved the look of the title bar and the dropdown button has been recolored.
