Aurora Browser

Aurora is a simple Mac browser that’s handy if you need reference material nearby. The browser has minimal chrome filling all available space with content and sits on top of all your other windows, so it doesn’t get lost. If Aurora gets in the way though, you can collapse it into its title bar with a quick click or global hotkey combination. You can also set the opacity of Aurora’s window in 10% increments so you can see what’s behind it.
