If you hack zen-mode like so

diff --git a/lua/zen-mode/view.lua b/lua/zen-mode/view.lua
index 2d170c5..c9c88bb 100644

   return {

 end

then you can add a config shift_amount that does what you're looking for

    {
        'folke/zen-mode.nvim', 
        event = "VeryLazy",
        version = "*",
        config = function(_plugin, _opts)

                window = {
                    shift_amount = 0,   ---- <--- add this
                    backdrop = 0.2, 

   --- etc

This feature is actually needed for text writer, and not only "left padding" but "padding" in both sides:

Without the padding, all text seems to be truncated (actually not) on the right side of the screen.

I know this is not a big thing for programmer, as 120 line width will allow most lines. But text editing is a different scenario
