How can I expand all nodes in the explorer tree based on depth level?

[pczern]

I'd like to expand all nodes in the explorer tree by default or just the first level. How can this be accomplished?

opts = {
  picker = {
    sources = {
      explorer = {
        on_show = function(picker)
          local Tree = require("snacks.explorer.tree")
          local root = Tree:find(picker:cwd())
          local open_recursive = false
          Tree:walk(root, function(node)
            if node.dir and (open_recursive or root == node.parent) then
              Tree:open(node.path)
              Tree:expand(node)
            end
          end, { all = open_recursive })
        end,

amazing, that works very well for the first level! Thank you!

When I try to open all nodes (e.g. subdirs) it seems like node.children is empty. I just need the first level but I am curious why all = true does not open them all.

function Tree:walk(node, fn, opts)
