Also display the subfolders in livetable when clicking on a folder

Steps to reproduce:

1. Create a new folder (F1)
2. Add some files to F1
3. Create a subfolder (F2) in F1
4. In file-tree, click on F1.

In the livetable you will see only the files prior added to F1, but not the F2 subfolder. It would be nice if also F2 is visible in the livetable.
