I'd like to hide the statusbar by default when opening Zathura (Which is normally done with ^n)
image of the statusbar (HIghlighted at the bottom in the red box)

In zathurarc, use
set guioptions none
From the man pages
guioptions
Shows or hides GUI elements. When it contains 'c', the command line is showed. When it
contains 's', the statusbar is showed.
· Value type: String
· Default value: s
Even though the value "none" is not mentioned explicitly, it seems to work.
