Sometimes you don't want to show the columns in an outliner, so now that we have a mandatory <outlinercols> element, it would be useful to be able to set hidden="false" on that to hide them all.
Two questions that beg answering: 1. If we were to have such a capability, why would we use hidden="false"? False means NOT true. That statement, if read aloud in English, would be "NOT hidden". In Spanish, "NO ocultado." 2. In what cases do you want to hide all the outliner columns but not hide the outliner itself? What would be visible in the outliner if all of its columns were hidden?
Setting hidden on an <outlinercols> would mean that you hid the actual column _headers_. This is very useful when you don't support any kind of sort, and the columns headers are just useless... It frees up some space.
The current implementation of outliner body depends on visible column headers. We need headers to get width and order of columns. Only workaround I know is to minimize headers height.
