Missing Node Editor Header Bar at Bottom I'm looking at the node editor and somehow ended up losing the header bar at the bottom of the node window (e.g., it had the "add" menu to add nodes). This was done when I dragged part of the window to try to resize it, but instead it was the menu bar and it reduced it to size zero instead of moving the window I was interested in.

Many suggestions say you can split the window and simply select the info or other bar you want...but the menu to do this has itself disappeared and a split window is a duplicate of the original with the missing bar:



How do I get the "add" and other node menus back if splitting the window never provides the menu to select what is viewed? Any new window has the same empty bottom bar as the bad window and no means to tell it to select anything different.
If header somehow disappeared and there isn't way to use "+" button to get it back, try using Toggle Header command from Space menu. In the current editor window it will hide the header if it's present and open it if it's hidden.
