I used an app called Xtrafinder that had this awesome feature, that the column width was always as wide as the widest file name (I really don’t understand why Apple haven’t implemented this 
)!
But a couple of macOS’s ago Apple started with the SIP (System Integrity Protection), and it became a mess to work with Xtrafinder.
My question is: Is there any app or way to always have automatically adjusted widths of columns in Finder?
