This is my own version of zenmode, highly inspired by nvim-tree.

Just use your plugin manager, I prefer lazy:

require("lazy").setup({
    "Snikimonkd/yazmp",
)}

Now you need to set up a keymap, or use it as a command (you can specify a width, default = 30):

vim.keymap.set("n", "<leader>zm", ":Zenmode<CR>")
-- or with width
vim.keymap.set("n", "<leader>zm", ":Zenmode 20<CR>")
