Docking Area
Somehow I deleted the docking area to the right of my viewport. Now the docking divider doesn't exist. I want to add the Aux Viewport, but I can't just drag the Aux Viewport tab and have it make a docking area. And if I set the Viewports to have 2 on the left side, those are only 3D View viewports, not for other windows.
Thanks.

Don't drag by the tab but by the edge then you should get a highlighted bar when it is in a docking position.
Excellent. Thanks much
