@benoitf I'm wondering, would it be useful in your case to also be able to flatten the Explorer. I know that Java projects often have very long package names such as (com.domain.package.task).

Instead of displaying the following in the Explorer:

+ com
  + domain
    + package
      + task 
        Task.java
...

We can optimize the display to:

+ com/domain/package/task
  Task.java
...

In essence, if we find that there are a single child node in a directory which itself is a directory then we can offer a flattened Explorer or at least be able to toggle to flatten. My only worry is finding the proper mechanism to add an entry in the middle, say package. What are your thoughts?
There is an issue present in VSCode for such a functionality microsoft/vscode#41627

@vince-fugnitto yes that's also a nice improvement like it's done on github explorer as well
to flatten view when there is only one folder in child.

I like that ❤️

@vince-fugnitto about your issue on entry in the middle, new Folder or new Package could contain a pre-populate content

I added a separate issue highlighting the proposal #4783 😃
