Vim has a non-removable status bar at the bottom. Nano has the same problem with its title bar. Surely there has to be an alternative for entering text in full-screen without any frills? I often jot down ideas in a full-screen terminal with large font size and a single line space becomes critical. For instance, my entire screen looks like below with Vim.

Looks like a great opportunity to switch to a Real Editor! :P. Emacs can do this. It also has a bar at the bottom, and can have some at the top, but all can be disabled. You will most likely just see the bottom one in the default setup:
To disable it, add this line to your ~/.emacs file and restart emacs:
(setq mode-line-format nil)
Or, to disable it only for this session, press Esc+: and then write (setq mode-line-format nil) and press enter. The result looks like:
If you also have other bars active by default, adding these lines to ~/.emacs commands will get rid of them:
To disable the menu bar, add this line to ~/.emacs:
(menu-bar-mode -1)
To disable the scrollbar, this one:
(toggle-scroll-bar -1)
To disable the toolbar, this one:
(tool-bar-mode -1)
You can install emacs with
sudo apt install emacs
Or, to install it for command line only, without GUI support:
sudo apt install emacs-nox
No matter which of the two you install, if you are running without a GUI (e.g. in a tty), running emacs will open the command line version and, if you are running with a GUI, running emacs -nw will open the command line mode in a terminal.
