3. Panelize

The will turn any tab into its own panel, which you can then drag around and reposition wherever you want on the screen. A panel is simply a browser window minus tool bars or the other usual user elements of a Web browser. This extension is handy if you want to turn a Web app, such as a Web-based painting app, into an ersatz, self-standing application separate from the browser portion of Chrome.

4. Split screen

The extension works this way: when you click its icon, it takes the contents of the tab you are currently looking at and the one you viewed before, and re-loads both inside a third tab, setting each within its own frame in a vertical split-screen. You can adjust the width of the two frames by clicking on and dragging side-to-side the vertical line separating the two.

We really like this extension, especially when used on ultra-wide screens. As an example, within one frame you can use a Web app (like writing on Google docs) while continuing to browse the Web in the other frame to look up information without switching to and from another tab.
