Auto coalesce nested folders when using `group_empty_dirs`

[oddlama]

I sometimes have to work with java projects, which have deeply nested folder structures, where many folders are completely empty except for a subfolder. group_empty_dirs is an awesome feature to tame that mess. What I'd wish neo-tree would do is to automatically peek into encountered folders to see whether they are otherwise empty, so that I don't have to enter each stage manually. It should be easy to detect this and would be a great UX improvement for group_empty_dirs. What do you think?

Neo-tree has been absolutely awesome and that's one of the only things I'm missing since I switched from nvim-tree last year. Thanks for making it.

It seems that it has been somehow address by #600

You can enable it by setting:

        filesystem = {
            group_empty_dirs = true,
            scan_mode = "deep",
        },

It is not the same though as it clutters the view on start with all these empty nodes being collapsed and visible.

Thanks @ghostbuster91 !

Does this achieve what you need @oddlama ?

Yes, this is perfect! Thanks for reminding me to test this.
