All-in-One Sidebar (AiOS) is a sidebar control, inspired by Opera’s. Click on the left edge of your browser window to open the sidebar and get easy access to all your panels. It lets you quickly switch between sidebar panels, view dialog windows such as downloads, extensions, and more in the sidebar, or view source or websites in the sidebar. It includes a slide-out button and a toolbar, all of which can be extensively customized.

You can set the orientation to left or right, set the minimum, default and maximum width and the behavior on browser startup. Furthermore AiOS provides enhancements for many built-in features.

Enjoy a clear browser window, more toolbar space and much more…
