[picker.explorer] How to make preview togglable in "main"

[xian-wen]

Currently, when I press <A-p>, the preview window is too small.

I know I could set preview to main to make it big enough:

    opts = {
      explorer = {},
      picker = {
        sources = {
          explorer = {
            layout = { preview = "main" },
          },
        },
      },
    },

However, this makes preview shown by default. How can I make this big preview togglable?

A workaround (without any custom config) would be:

1. <A-w> to focus on the preview window
2. <Leader>uZ to zoom to the full screen

But that's a little bit complicated.🤣

I managed to make it work with the above configuration by using the below autocommand.
So this can be used until upstream is updated to allow easier configuration for this.

vim.api.nvim_create_autocmd("FileType", {
    group = vim.api.nvim_create_augroup("SnacksExplorer", { clear = true }),
    pattern = "snacks_picker_list",
    callback = function()
        local pickers = Snacks.picker.get { source = "explorer" }
        if #pickers == 0 then
            return
        end
        vim.schedule(function()
            pickers[1]:toggle_preview()
        end)
    end,
})

You can now do preview = {main = true, enabled = false}
