List of notebook files should include more file information

[mjbright]

From the File tab of the root view we see a list of files in the current directory.

It would be useful to see more information about files, e.g. have a button to toggle between the existing "ls -1" style and "ls -altr" style outputs.

In the case of notebooks in that list, it would also be nice to know the number of cells in notebooks (and why not the kernel).

The use case for this is that when experimenting we can end up with a lot of Untitled files that can probably be deleted ... it would be nice to have some indication of contents without having to open each file.

The number of cells will be a no-go, as it would require to actually parse the notebook, you cannot potentially read and parse several Gb of .ipynb files to create a tree view.
(unless notebooks are stored in DB, so we can think about it)

But for running notebook, it would be possible, as the kernel is already started.

an overhaul of the Dashbaord is planed, but someone need to do it :-)

@gnestor : is this still on the development horizon for notebook or a candidate for JLab? thanks!

Perhaps the kernel of a notebook could be indicated using its icon?

The FileViewer in jupyterlab doesn't have much screen real estate to work with, but I would say that a feature like this should be implemented in lab at this point.

Nonetheless, if @mjbright or anyone else would like to contribute this feature to the notebook, then it would be very much appreciated!

@gnestor, can I work on this?
Also, in regards to indicating a notebook's kernel, what icon are you referring to? Is it the bright green notebook icon to the left of the notebook?
