DockView 2.1.7 – View previews of applications from the Dock

DockView is a utility that adds a preview of the windows of the selected application in the macOS Dock. You just need to bring the mouse to its icon and thumbnails of all its windows will appear. By clicking on the one you need, you will immediately go to it. Through Window Thumbnails, you can quickly close, minify and manage windows.
 
Features

Fast switching between windows of the selected application
Window management (minimize, de-minimize, close)
DockView doesn’t modify the Dock or any system file.
