Yes please! I would love this feature as well. I use window autosize, but I'm still constantly having to resize columns to see everything (no pun intended), most often the path column, sometimes the name column as well.
Even more amazing -- not sure if this would even be possible -- would be if user-definable columns could be chosen for auto-sizing (including with window size changes). Sometimes I need to see the full length of the name/path column while not necessarily needing to see the full name/path column. It just depends what I'm working on as to which I prioritize having to see the full width of name, path, other times both of them together.
But even just a general column-autosize feature would be fantastic!
