It'd be great to have a way to highlight some files, for instance some configuration files (e.g. package.json) so they can be quick to perceive when the drawer opens.

Describe the solution you'd like.

easy way to configure them,

return {
  "neo-tree.nvim",
  opts = {
    filesystem = {
      highlight_items = {
        'package.json'
      },
      ...
    },
  },
}

Describe alternatives you've considered.
