Modifying columns in FILES app

The columns in the file pane of FILES can be customized to a point. Name, size, type, location, etc.
Once I have a window with my columns set up as desired, can I then make that the default for all FILES windows?
Bonus points question!
Is there a way to add a new column for Length, duration, etc available?
Maybe my answer is a different file browser...
Thanks, all

If you want to customize the file browser nemo is the way or Dolphin (KDE).
