Setting custom icons

If you want to set custom icons for elements like tabs, file explorer, file finder, etc, just add this following config to the entry hooks.after_setup in better-vim.lua file:
better-vim.lua
return {
  hooks = {
    after_setup = function()
      require("nvim-web-devicons").set_icon {
        res = {
          icon = "ﬦ",
          color = "#e6484f",
          name = "ReScript"
        }
      }
    end,
  },
}
Since we’re using nvim-web-devicons as our icons plugin, you can see more about custom icons on its official documentation.
