skip through empty directories

[litoj]

Is your feature request related to a problem? Please describe.
I'm always frustrated when I open a java project and have to open 10 nested directories before I get to the file I am looking for.

Describe the solution you'd like
When I want to expand a directory that contains just another directory, expand them all until the directory contents differ from 1.

Describe alternatives you've considered
Expanding all subfolders, but that is too much.

Set nvim-tree.renderer.group_empty to true.

From the looks of the code there is not a way to use a custom function to label these possibly very long paths like we can with root_folder_label. It would be very handy if such a feature was possible.

That should be possible. Your function may be a little... complex.

Please open a new feature request specifying exactly how you think the option should behave as well as with an example function.
