In this mode, tintii runs as a separate application. On launching the application, a small splash screen will appear for a few seconds introducing tintii, along with an empty window displaying only the menu and toolbar. Some options will be disabled at this stage. Use the File > Open menu item or click the Open icon on the toolbar to open an image and work with it. Multiple images may be opened, each creating a new tab below the toolbar. Click on a tab to change the visible image. Click the X icon on a tab to close the associated image.
