Europa is a desktop client for JupyterLab that provides native app experience using standalone windows and keyboard shortcuts.
Europa supports all the keyboard shortcuts for JupyterLab that you'd expect in a desktop application (like Ctrl+Tab to switch tabs, Ctrl+W to close a tab). More details are on the Keyboard Shortcuts wiki page.
You can either grab a portable app for linux/windows or grab OS specific installer from the releases.
