Minor mode that hides/masks your modeline
Provides `hide-mode-line-mode`. A minor mode that hides (or masks) the mode-line in your current buffer. It can be used to toggle an alternative mode-line, toggle its visibility, or simply disable the mode-line in buffers where it isn't very useful otherwise.
