OT: How to modify Google Drive file list info?

[joe at actionline.com]

Why does the Google Drive list of files and folders include a "LAST" date
modified in some lists but that date info is omitted in other lists, as
seen in the two screen shot examples shown at this link:

How can I change the column widths to make them narrower/smaller so the
list elements are closer together and easier to read?

And, how can I add a "LAST" date modified column in the list where that
important information is missing?
