If you've ever used Total Commander or even Windows 7+ native file explorer it's very hard to go back to or use Finder. Keyboard shortcuts, tokenizing/detokenizing file paths, opening in terminal, searching within files, search for duplicate files, bulk rename, plugins, and more.

Whenever I have a new Mac I spend a couple minutes customizing Finder: adding things like the Path button, showing the Path bar, showing the Status bar, etc. I get that it's supposed to be simple but it's surprising to me that such basic things aren't in the starting configuration.

I do love the spacebar preview though :)
