Option to merge statusline and command line into a single line

[nik-rev]

This is currently how the bottom of my editor looks:

So there is an entire line of whitespace that could be used by actual text instead

Can there be an option, like editor.statusline.merge (boolean) which will hide the statusline when there is a message ? so instead of this:

The error message will instead replace any text on the status line while it's shown

And when we type : command, it will also replace the status line

I would love this. Neovim has this option and it works well.

I would like to have this option. This is how the statusline in Tmux works.
