In Docking Mode, the Sidebar windows are always displayed in the browser. You can also change the size and shape and/or move it around wherever you feel like.
You can make your sidebars in Docking mode by the following steps.
- Click on the Peg mark on the top-right corner of the sidebar. That will keep the sidebar open all the time.
- Clicking on the Peg mark again or [X] will hide the sidebar.
- If you want to bring it back again, go to View > Sidebar or use shortcut key such as Alt+4
From Right-Click Menu
Once the sidebar is in Docking mode, you can right-click on the title bar area to switch the mode.
