Viewport (alpha) is a Chrome extension that allows users to open tabs in separate minimalistic windows, aiming to help individuals with limited screen real estate, such as laptop users, maximize their workspace. The main feature of this extension is the ability to swiftly convert a regular window with various UI elements to a minimalistic popup window, and vice versa, while maintaining the original window's size and position. This conversion can be easily triggered using the default keyboard shortcut Ctrl + Shift + Period, which can be customized in the "chrome://extensions/shortcuts" settings.

Moreover, Viewport (alpha) enhances user experience by displaying the current URL on the title bar alongside the original page title, facilitating tasks like saving pages to PDF or printing with the original title. Users can toggle this feature using Ctrl + Shift + Alt + T. Additionally, the extension offers a convenient way to copy the current URL to the clipboard with Ctrl + Shift + Alt + U, providing quick access to share or save URLs.
